How to make an application in the app store. How to create an iOS app yourself
Anyone who plans to start a career in this activity is trying to find out what an iOS developer should know. Others are convinced that this option is too complicated - after all, programming is not given to everyone. But there are those who know: water does not flow under a lying stone, but with effort you can move mountains to the right place. Specialized offices currently provide training in iOS development. These are mostly quite expensive private schools. Those who want to save money take iOS development courses online: there are quite a lot of freely available resources on the Internet. However, a good result will be obtained only with maximum effort.
Money: how to get it?
Demand for tutorials on iOS development has become especially high since 2014. It was then that an author from Vietnam released a toy for this platform that quickly gained worldwide popularity - simple in execution, but difficult to complete. The project was named Flappy Bird and brought its creator several hundred thousand US dollars in just a couple of months. Then many people who were able to see the future of technology and predict what would be in demand after some time realized that it was time to master development from scratch for iOS. Indeed, currently there is a great demand for specialists in this field, but only those who can write high-quality code get good money.
Developing applications for iPhone raises a real sea of questions for many. It is completely unclear where to start, how to apply existing knowledge, where to get training to get good level skills. Where to start developing applications for iOS? Many modern books answer this question, but large volumes and complex presentation of information make them difficult to access for non-professionals.
Basic Skills
Usually lessons iOS development begin directly with writing code, as well as explanations of techniques that may be useful to a novice specialist. But it’s not always the case that someone who is already familiar with a suitable programming language takes on the task, so it’s more correct to say that the optimal initial stage is researching a suitable tool. Most often, iOS developers use Objective-C. The language belongs to the group of object-oriented ones. From the experience of many iOS developers it is clear that it is more convenient than others when creating applications for smartphones. However, not only for Apple technology - it can also be used when working under Android.
If by creation mobile applications A person who has previously mastered a language from the object-oriented group decided to take it up, then working with a new tool will not cause problems. All OOPs are quite close to each other and follow a similar logic. How to become an iOS developer if you have code creation skills? You need to pick up a book that explains the main features of Objective-C and practice programming elements. It takes a little time, but gives excellent results. A novice specialist will master the syntax, understand what capabilities are hidden in the language, and how the code can be organized with maximum efficiency. It is worth remembering that if the code is of high quality, then the iOS developer is highly valued. The salary will be decent - hundreds of thousands of rubles. But those who write complex, incomprehensible, confusing code get much less.
Let's go from scratch
However, developing applications for iOS is available not only to those who already have experience creating code. You can safely take on mastering the area without having specific knowledge and education - this is a gainful endeavor. Of course, Objective-C is not the simplest language, including in the OOP category, so it will be easier to cope with it if you first delve into the logic of this entire group of software tools, and then pay special attention to the specifics of a particular option. As experts say, application development for iOS must take into account three main features inherent in a code creation tool: polymorphism, inheritance, and encapsulation. These are the whales of the world of programming for Apple smartphones.
An interesting one was released in 2014 software development- Swift language. It was introduced by Apple themselves, presenting it as a means for creating applications for their technology. The main goal of this product is to make the code development process simple and fast. Swift is designed for smartphones, so it makes developing iOS apps much easier than trying to tailor products that were originally designed as a way to write code for desktop machines running other operating systems. Swift has gained some popularity - not only code for applications on smartphones and tablets is written in it, but also programs for systems like UNIX.
Don't spray!
Mastering Swift tools is reasonable if the programmer is already familiar with object-oriented programming languages. You definitely need to devote time to mastering Apple development even if a person is able to write code in Objective-C. But if you still have to master this indispensable tool for creating mobile applications, then you don’t need to be distracted from the main task. Swift, of course, is important and necessary, but it will be possible to tackle it later - when you manage to “defeat” Objective-C. And at first, this new tool alone will be enough to load the brain full program. As experts say, this is definitely not the simplest of programming languages, but it is quite flexible and provides many opportunities for creating effective code.
Toolkit: useful for a programmer
iOS app development involves interacting with several tools to make the app optimized, functional, efficient, and aesthetically pleasing. Traditionally, the most important and first mentioned is the development environment. When creating products for Apple mobile devices, it is best to turn to XCode. It is completely free and can be downloaded through the official app store. Distribution is free, everyone has access.
The next tool for developing applications for iOS is an editor that allows you to correct the created code. It is better to give preference to the light ones, simple programs. Traditionally, the most popular are those with a backlight function. Just a few seconds - and the already written code is running. It takes a little time to detect erroneous lines and correct them; this does not load the resources of the machine on which the programmer is working.
The graphics are worthy of attention
Surprisingly, many novice programmers do not devote any time to this component of creating a program. For iOS application development to become a process that culminates in the release of a functional, attractive application, you need to master the tools that allow you to adjust appearance programs. Vector graphics technology is best suited. This will make it possible to create unique images, icons that give the product originality and individuality. Despite the fact that some will say that decoration is too difficult a task, you cannot achieve success if the product does not visually attract the user. Especially these days, when there is competition in the store Apple applications It’s simply huge and there are options for every taste and for every purpose. You will be able to oust them and attract attention to your development in the case when the new product not only functions well, but also looks beautiful.
The right start: a clear plan
Without creating a detailed plan, you should not count on any successful results. Structuring is not the easiest task, but it definitely deserves attention. Before you start coding, you need to set aside a few hours and sit down with a sketchbook to create an optimal plan. As part of planning, it is important to form an idea of the design solution of the product, to formulate who it is intended for and what functionality it provides.
Thinking through the design begins with formulating the concept. You also need to choose which functions to implement in the program, give them a brief but succinct description, and also indicate all possible schemes for the interaction of elements, including transitions. It won't hurt to draw sketches important elements. When deciding on the functionality, you need to select one task to solve new product, and formulate the features of the application, focusing on this goal. As for the audience, it is important to understand that age, area of interest, lifestyle and gender strongly influence both the tastes and the purposes for which users download applications. Having chosen your target audience That’s right, you can successfully choose a design solution and additional functionality.
Project: first went
Your very first project doesn't have to be complicated. You could try creating a learning app that only has one screen. To do this, open XCode, create a new project, set the platform for use the right tools optimization, after which the type of software product is selected. To make the environment easier to master, you can start with the Single View Application. A unique name is given to the project. IN standard mode The programming environment assumes that writing will be done in Objective-C. If the programmer wishes to use another tool, he must refer to the list of possible languages. Among the menu items there is a person responsible for the language; there you should assign the most convenient option from those available. After this, switch to universal mode in the Devices tab.
In the navigation panel, a hierarchical structure is expanded to search for the Main.storyboard document. When you select it, you can see the Interface Builder key - it is activated, and selected from the shown panel necessary tools, move them to a comfortable position, align them, and make adjustments. To reflect elements in the code, each object is selected with the mouse held down. Ctrl key, is moved to ViewController.h, which initiates the launch of the Outlet dialog box, where you can specify the properties of the formed connection. Here the programmer specifies the name by which the element can be called in the program code.
To create an effective action handler, you will have to repeat the above chain of actions, but using the ViewController.m dialog box. A method with an encoded program is formed inside it. The machine will refer to it whenever it needs to interact with the component.
Verifying the result: testing
IN large companies This task is carried out by several employees at once. The methodology used is quite complex. First, cases are formed, which indicate what actions need to be tested, what results the program should produce, and real experiments are carried out with the results recorded. For a novice developer of mobile applications for Apple's OS, everything is somewhat simpler (but also more complicated at the same time). Here testing falls entirely on the author of the code, but there are usually few tasks themselves that need to be checked, so you can carry out the operation in manual mode. To do this you will need an emulator through which you run software components. During the interaction, you can find which decisions were unsuccessful, which mistakes were made, note this for yourself and correct it when finalizing the code.
When testing on your own, it is important to imagine yourself as a third-party user who has nothing to do with the code. Moreover, you need to imagine yourself as a critic, interested only in mistakes, a person who does not care positive qualities programs, but only negative ones. We must try to break the program everything possible methods. Should numbers be entered? Enter letters in this field. You need to press the key quickly - press long. In short, testing is the time when you need to break all established rules and recommendations.
I don't want to, I won't!
Not every programmer is ready to take on own program, using such barbaric methods of interaction. Others find it a boring task that is not worth their time. To get rid of unnecessary work, save hours and eliminate unpleasant situations, you can involve freelancers in the project. There are specialized sites where you can find people who are willing to look for all sorts of bugs in a new product for a small fee.
As professionals say, entrusting the search for errors to a third party is good option, much more effective than independent decision problems. The freelancer has no idea what the program should do and what it shouldn’t, so his consciousness is not “clouded” by excess information. It is easier for such a person to test applications, which means he will be able to find more problems and eliminate them before the official release.
More audience!
If experiments with freelancers have shown that the application is ready to “float freely”, it’s time to publish it. To do this, the product is uploaded to the AppStore. Software environment XCode, when you press the keys responsible for this, will create an assembly of the type that the programmer has previously installed. You must select the Distribution option. The compiler will create a file and write it to the directory assigned to the project. The programmer then manually packages the document into a ZIP archive.
The next step is to use the iOS Developer Center interface and find the iTunes Connect menu. Through the management and adding functions, you can go to the profile page of a new product. You will have to fill out all the fields specified here yourself. You can prepare information in advance - for example, while the project is being tested. You need to write a unique description, provide contact information, make a small icon (512*512 resolution), and screenshots.
What to do next?
To publish an application, you must use a special software product, designed for loading new objects - Uploader Tool. You can download it from the link that the system will open when the user goes to the ready-to-download menu. A connection to iTunes occurs automatically, after which the shell itself determines what projects the user has. All you have to do is select the one you need, and it will be loaded by the program, without any special effort.
After downloading, the new product is sent for verification, which usually takes several days or even weeks. If the result is negative, the developer receives an email notification listing the reasons for the refusal. If you can eliminate all the shortcomings, you can resend the new product for moderation.
News is important
The developer of XCode releases updates for this framework quite often. The latest version must be used. This not only makes it possible to work with a program where the number of errors is minimized, but also allows you to regularly learn about all the updated functions. Using the newest and most powerful interface, the programmer simplifies the task assigned to him. In addition, Apple regularly releases iPhone updates SDK. The most up-to-date tools will be the key to a good result.
A fly in the ointment
If the application successfully passes the verification, it goes into the public zone. The developer will probably receive a lot of negative feedback at the very beginning. Not all of them are constructive. You need to be able to analyze information from users in order to improve your product, but you need to sweep away unnecessary and meaningless negativity, without letting it hurt you and undermine your faith in your abilities. If a person behaves rudely, and there is no benefit from his criticism, you can simply not pay attention to the messages he leaves.
Have you ever thought about how applications for iOS and OS X are created, of which there are millions? iPhone owners, iPad and Mac used every day? We know that many people have thought about developing programs for Apple devices, but beginners, as a rule, are afraid of the difficulties in the learning process and studying textbooks on their own.
The profession itself “application developer for iOS and Mac” is universal: it combines knowledge of two programming languages - Objective C and Swift. The first is the main language, built on the basis of the C language and has a simple syntax. Without this language, people will not be hired to work in a mobile application studio. But Swift is a relatively new language: Apple introduced it in 2014, it is integrated with C and runs faster than Objective C and Python, allowing you to create any programs - both games and useful applications.
Nowadays there are only a few specialists who know Swift, so they are in great demand on the market. Just go to any HR platform to see the average salary of iOS developers - 100 thousand rubles. Experienced programmers have a salary of several hundred thousand rubles + various bonuses from the company.
To get best result for a short time and a guaranteed internship, you can use the GeekBrains service. It includes both Objective C and Swift, which means that you essentially get two specialties instead of one. Companies sell smart iOS programmers like hot cakes, so they don’t sit without work for even one week.
The learning process is an online broadcast of lessons, so you can study from anywhere in the world. Specially developed unique technology makes remote learning even more convenient than face-to-face learning. Do your homework, and if you couldn’t be in class, watch it in the recording. Here's what a typical lesson looks like on GeekBrains:
Why online courses? They have an obvious advantage over universities in terms of time spent and at the same time provide the opportunity to earn practical experience and get a guarantee of results. 7 out of 10 service students find work while still studying, since GeekBrains provides a guaranteed internship. In addition, students gain invaluable experience in team development and a portfolio case. Without the latter, it’s almost impossible to get a job now.
For example, this is what your resume might look like after training.
Every day the number of people dreaming of learning how to create programs is increasing. After collecting information on the Internet, the idea comes to them that the most promising is the development of applications for iOS - operating system from Apple. In fact, dreaming is one thing, but programming is another. Create own application not easy. But it’s not prohibitively difficult either. What is needed for this?
Programming language
To write programs for a specific platform, you need to use a specific programming language. App development for iOS and Android is different. If you need to select the Java language for the platform from Google, then for iOS choice stands between Objective-C and Swift. Long time Development for the iOS platform was carried out only using the Objective-C programming language. Even though it is many years old, it is still being developed and used by a large number of developers. But its downside is the high barrier to entry.
Since the most important source of profit Apple is its app store, employees are interested in more useful and interesting utilities. For this reason, a developer conference is regularly held to talk about changes in operating systems. In 2014, developers were shown newest language Swift programming, which is used to develop applications for iOS. Swift is easy to learn as it has a very simple syntax and is strongly typed. This language is very suitable for those who want to learn on their own.
What you need to get started
In addition to basic programming knowledge, you need to have the following:
- a computer or laptop with the OSX operating system on board;
- Xcode development environment, which is free.
This set allows you to run applications in a special simulator directly on your computer. But keep in mind that in the future you may need to pay $99 to get an annual subscription to the developer program. After payment you will be able to:
- run developed programs not in a simulator, but on real devices;
- place applications in the App Store;
- download new versions of the development environment and iOS.
In new versions of Xcode, a sandbox element called Playground has appeared. Here the developer can experiment with a new programming language.
Many people want to start writing programs, but they think it is extremely difficult. Of course, in order to become a professional, you need to have a lot of knowledge and vast experience behind you. But in order to create small application, there is no need to be a professional.
Where does the development of applications for iOS and Android begin? Learning happens by doing. Therefore, we must start with it. A lot of theory is not always good. After all, if a person reads ten from cover to cover, he will not. We need to act.
Playground
This sandbox is a wonderful environment for learning a programming language. What does she look like? The user enters a line program code and immediately sees the result of execution. Once it becomes clear that the written fragment works as it should, you can simply transfer it to the project. Using the sandbox, you can solve problems such as:
- mastering the syntax of a programming language;
- improving programming skills by experimenting with new APIs;
- performing simple arithmetic calculations;
- developing a new algorithm and monitoring its every step.
iOS app development: where to start
Theory is, of course, good, but, as mentioned earlier, practice is needed. In order to get acquainted with the sandbox, you need to launch the Xcode development environment. After launch, the user can see a window in which it is proposed to create a new project or launch Playground. We need a second point. Now you need to come up with a name and save the “sandbox” to any convenient location on your computer. By the way, developing applications for iOS on Windows is also possible, but then a large number of problems will need to be solved. This includes installing a pirated operating system and editing important files, and a lot of errors and crashes.
After saving, the very Playground that is needed will be launched.
At first glance, there is nothing interesting here. But as soon as you enter your code there, the appearance will immediately change.
To get started, you can try writing the following:
for var y = 0; y< 10; ++y {
println (“result: (z)”)
After this, the sandbox will change its appearance. The column on the right (results pane) shows the values for each row that are obtained after execution. Also in the right column you can enable the display of a time panel, which makes it possible to track changes in the selected expression over time. The console output with the text that would be output by the program is also displayed here.
Commenting code
Development of applications for iOS, as well as for other platforms, is not complete without comments, which are needed to make it easier for the developer to navigate the code. Comments are lines that are ignored during program execution. They can be either single-line or multi-line.
Variables
So, applications are written in a programming language. The basis of any language is variables. Developing applications for iOS and Android without using variables is impossible. As the name suggests, it is a container that holds a mutable value. Each variable must have a unique name and can contain both numeric and text values. In the Swift programming language, variables are defined using the words var and let. In the second case, the variable cannot be changed and must be initialized when declared. In the first case, the variable is initialized immediately before use.
Every variable has some type. These can be strings, floating point numbers (fractional), boolean values (true and false).
Output of results
The result of the program execution is output to the console. What is it? This is what allows the user to interact with the computer. Thus, the output console used to be called the monitor, and the input console was the keyboard. Now the meaning of the terms has changed a little. This is the name of a program window intended for input and output of commands. Developing applications for iOS often requires the output of some data. To do this, the Swift language provides the print and println commands. The first differs from the second in that it automatically starts on a new line.
Functions
Following basic concept in programming - functions. This is a certain sequence of actions that perform a specific task. Each function can take some values and also return a result. To use this construct, you must first declare it using keyword func. It is followed by the name, as well as parentheses. If a value is to be returned, its type is indicated after the brackets. If there is no return value, then the type can be omitted or an “empty” type – void – can be specified. The parentheses contain the values that the function accepts. To call a function, specify its name and values for the arguments.
You can make sure that the parameter name is required when calling a function. To do this, it is framed with the “hash” symbol.
So you can write some useful features, which can, for example, calculate exchange rates and convert one unit of measurement to another. Every time you need to use them, you just need to call these functions, and not write the code again.
What now?
So, as can be seen from the above, developing applications for iOS with your own hands may well be within the capabilities of everyone. The main thing is to learn the basics of the programming language, become familiar with the development environment, and practice a lot and often. It is practice that makes significant progress. But what is described here is just the beginning. There will be a lot of interesting, complex, and exciting things to come in the world of programming. This will help you always keep your brain in good shape, create something new and earn good money. After all, Apple technology is used all over the world. Therefore, your application can be appreciated by millions of people.
For managers and ordinary people
You often hear the phrase:
Shouldn’t I make an app like this for iPhones!?
Many people really think that creating an iPhone application from scratch is simple and fast, and earning millions is just around the corner. Let's try to understand this matter from the point of view of a person full of energy, but who has no idea about Apple ecosystem for developers.
Idea
Any project starts with an idea, and based on this, it may turn out that the application cannot be made. Developers I know have turned down jobs for a variety of reasons:
- It is impossible to determine the user’s position in the room more than five meters;
- It will not be possible to determine whether a person is on an airplane, what country he is flying over, and the moment of crossing the state border;
- There is no way to find out a person's phone number (unless the user enters it themselves);
- “If it’s just a website designed into an application, then it will be wrapped up”(we are talking about the review of the application by the App Store team);
In addition to what cannot be done, there are a number of things that can be done, but with certain restrictions. However, we will go further.
Team
The implementation of the idea can be ordered from companies that have already made hundreds of applications, or you can assemble your own team. Experts already understand everything, but their services will cost accordingly. Therefore, we will consider our team's option.
I will intentionally skip the recruitment step because this applies to any project, not specifically iOS development.
It’s hard to believe, but you can only write applications for iOS on Macs. Therefore, each developer will need one macOS device and one iOS device (there are some ways to get around this limitation, but we won't touch on them). He/she will write code on a Mac, and on an iPhone they will see what comes out of it. You can also hope that an iOS developer will come with his own devices (this is not a rare case).
The cheapest option is to buy everyone a used one. mac mini with a keyboard, mouse, monitor, a set of cables and some iPhone 5s. By the way, from now on you can consider lightning cables consumables: they break extremely quickly.
On top of that, you will need to get an “Apple Developer Organization Account,” which costs $99 per year and allows you to manage developer access, devices, and so on. You can get by with an individual account, but it costs the same, and it does not have team capabilities.
Interface Apple management Developer account for organizations
Design
Developers will create the basis of the application, its main capabilities. But the lion's share of positive emotions during use is generated by design. For this you will need special person who will think through GUI, will take a few mandatory pictures.
At a minimum, the designer will need the following:
- Application icon in various sizes(under various types screens);
- Application pictures (screenshots) for each supported screen and language if the picture contains text (developers can also take screenshots, but often additional infographics are added to them);
- Each picture that is used in the application, in all the right sizes(2–3x);
If you want a truly high-quality application, be sure to ask the designer:
- Drawings of all application screens (exceptions can be made for similar screens);
- Pictures for all pop-up messages, notifications;
- For all elements where there will be animation - think through and draw it;
- A map of transitions through the application - user flow, you can ask for it one of the first - this map greatly helps to identify the main and additional screens and their contents;
Example user flow from UBER for the “Take me there with UBER” button
At most, hire a designer full-time and work with him to create a truly user-friendly and enjoyable application that everyone can use (a subtle hint of “accessibility” - when the application is suitable for people with disabilities).
Testing
It would seem that all the pieces of the mosaic have been assembled, what is missing? We forgot about the people who will use your application and find errors in it. By the way, don’t expect that all developers immediately produce absolutely correct code. It's okay to make mistakes, but our application must be perfect. Therefore, before it gets into the store, it must be examined far and wide.
These issues are dealt with by testers; it is advisable that they have experience working specifically with iOS applications. Question: how will they do this?
Naturally, devices will also be needed here. It's good if you find all kinds of combinations iOS versions, types of iPhone/iPad, screen resolutions that you plan to support. But there are various workarounds and additional options:
- You can support only a few types of devices at first, and then modify the application for the remaining ones. However, Apple doesn't really like it when an app is locked to just one type of iPhone unless there's a clear reason for it.
- You can test some of the functionality on the Simulator (this is a program for macOS that emulates real iPhone). In it you can set both the screen size and the device type, but not everything can be tested: only on real devices you can check the work with various sensors(gyroscope, accelerometer, compass, ...), TouchID, push notifications.
- Be sure to test the application in conditions of poor or no connection (of course, if the Internet is actually used);
- Make sure that the application does not drain your battery too much;
- In the case of a large application, evaluate the need for automated testing: go through hundreds of forms in each new version complicated and not very rational.
And don't ask developers for an “installer” for the application they make. In the Apple environment, it is impossible to download the file to the phone, install it and run it. One of the developers will have to set up delivery of new versions to all phones where it is needed. There is no other way.
Everything is ready to launch!
So, there comes a time when the application is ready to appear in the App Store. What other surprises await us?
First, the application needs a name. If the application area is popular, then everyone is short and beautiful names may already be taken, since the App Store does not allow two applications with the same name. All that remains is to come up with it in the form of “XYZ - application for XYZ”. This name is displayed only on the application page itself in the AppStore and does not have to coincide with what will be written after installation under the icon of your application for a specific user. This text is not subject to uniqueness restrictions.
There is one small trick with the name of the application. When you create an application in iTunes Connect, you can specify its name before the version for publication is actually ready. Thus, you can take your name a little in advance, although Apple has already does not guarantee the duration of this period.
Secondly, you need a description. How easily the user finds your creation will largely depend on it and the name. By the way, if several languages are supported, you should immediately think about which of them the description and title will be translated into.
Thirdly, if not immediately, then after a couple of days in the store you will begin to wonder what users are actually doing in the application. This is where a metric comes to the rescue, which anonymously collects statistics. open screens, shopping and any interesting activities. The implementation of the metric should be taken care of immediately, and on its basis it is worth drawing conclusions about improving existing functionality and creating new functionality. You will probably be tempted to save each user's actions along with their email or name: remember, this is not a good thing to do, because no one likes to be spied on.
Fourthly, you will have to undergo an application review by the App Store team. The review takes about two weeks, and all the most hidden features of your application will come to light. Here are some tips for successfully passing this test:
- If a login/password and registration are required to access the main functions of the application, be sure to provide the App Store team with test login data for the application. They will need a test one to make purchases. credit card. If for normal operation you need some accessories - be prepared to send them to Apple too;
- If there are sales of something in the application, there must also be a user agreement containing the phrase that Apple has nothing to do with it, and your company is the seller. This text should be available in all languages that you support;
- If you sell virtual goods, you will most likely need to use “in-app purchases”;
- Make sure that no prohibited APIs are used and that the overall application does exactly what it promises.
If all points are honestly followed, then in about two weeks your application will appear in the store.
Application in the App Store
We sincerely congratulate you. Your first creation will finally fall into the hands of users! It's time to look back at the path you've traveled and think about new versions of your application.
Mobile applications are what every smartphone owner uses today. At any time you can look up the way to the desired place, translate an unknown foreign word, read new book, listen to your favorite music. That's what smartphones are all about: limitless possibilities right here, right now. Now you can not only use popular apps, but also create your own. We’ll figure it out together in the article how to do this.
Writing a program on your own today is a prestigious and profitable business. A potential developer has a chance to make good money, provided that his application is in demand.
Therefore, it will be a shame if you waste your time creating a program that will not be used. To prevent this from happening, a novice developer needs to study this fascinating process in detail. The demand for an application depends not only on consumer needs, but also on the skill of its author.
There is another side to the coin: the average person simply wants to come up with a program that is more convenient than others already proposed today. A program that he will use himself. For example, an improved calculator, organizer or dictionary.
If you want to make money from your program, do not forget that it must be original. Trivial photo editors or a new email client will not help you get rich. Think over the idea in advance and determine how your creation will compare favorably with other similar ones.
