Are you a fan of software programming and you’ve been very fascinated by the world of iPhone’s Apps? Then you should try and start developing an app of your own to be published on the App Store.
All that you need is a Mac and a good idea to turn into application. For the rest, with a little of experience and good will, you are going to learn how to develop an app for iPhone, iPad or iPod Touch. It’s much easier and faster than you can imagine. Want to bet?
If you want to discover how to develop an app for iPhone, iPad or iPod Touch, the first step you need to do is to visit this page of the Apple website and join Apple IOS Developer Program as an individual developer. This will allow you to test the app you write on your iDevice and then to publish your app on the App Store. If you want to be a registered Apple developer, you must pay an annual membership fee of 99 $.
Once you are signed up for the developers program for iOS, you have to open the Mac App Store and download Xcode, the software through which you can create app for iOS and you will have access to a graphical editor, a code editor and several pre-defined templates that allow you to become familiar with the development environment. Together with Xcode, you’ll also have installed the iOS software development kit (SDK) and iPhone Simulator, an iPhone emulator that lets you run a test on the first app developed without using a real Apple device.
To develop applications for iOS you must use the Objective-C language, which is quite intuitive for all those who have programming experience in Java and C++. If you are not one of them, you can search on Google for guides to Objective-C (there are plenty) or refer to Apple’s official website where there is a nice introduction to the platform.
The Objective-C is a language focused on objects, this means that, during the development process, you must focus your attention on the creation of objects- It’s all explained in this comprehensive documentation on the Apple site.
As for the user interface, try to design your application following the guidelines of simplicity and human interfaces. In short, give a familiar design to your app trying to make them user-friendly for those who are completely ignorant of technology. To better understand what I’m saying, try to open the Calculator application on your iPhone: anyone could use it. Why? Simple, because it resembles in every way a real calculator and therefore does not need any explanation or introduction to be used.
Once you’ve finished developing an app, you need to test it in order to find bugs and fix them. As mentioned above, you can test the app directly on your computer using the iPhone Simulator but this applies only to the first few tests. Following you need to transfer the app on your iPhone and test it directly on the device to find bugs that would otherwise remain hidden.
To run your app on an iPhone / iPad / iPod Touch real, you must register your device at IOS Developer Program, create a certificate for signing the app and create an app ID that identifies your application. The single developer license allows you to test the app on up to 100 devices.
After performing the testing phase, when you believe that your application is ready to be downloaded or purchased by the public, you have to send it to Apple via iTunes Connect and wait until it is approved by the heads of the App Store. The process usually takes a week or two, so do not worry if you do not get “answers” immediately after submitting your app.
