Developing your own app is a nice goal. But how do you program such software? The following guide will help you get started.

Programming software is challenging

Every software you use had to be programmed beforehand. Even Apps are software products that you can use for mobile devices or other systems (such as Facebook etc.) have to program.

  • Programming is an exciting and challenging activity, depending on your talent and enjoyment.
  • The biggest factor in programming is that the technologies behind it do not change fundamentally, but the innovation cycles are getting faster and faster. So it can happen that, despite "old" development knowledge in Java, you are hopelessly lost today, because both the tools and certain coding standards have changed.
  • This is particularly true of the mobile area and apps. There are not only numerous different standards here - Android, Windows Mobile, iOS etc., but also different technical approaches - from Java (with Android) to C # or Objective C.

How to develop apps

The example of the iPhone shows what you need to program a iPhone-App need:

Programming iPad apps

Apps are becoming a trend - and not only on the iPhone, but also on ...

  1. You need the hardware first. In addition to iPhone / iPad, above all a system with Mac OS X.
  2. Now download a development environment (e.g. B. Xcode).
  3. For Xcode you need the basics for development for iOS, which you can find in the Developer area from Apple.
  4. You also need to license yourself as a developer with Apple (for a fee).
  5. Create a developer profile that you need for the download.
  6. Equip your devices with the appropriate "provisioning profiles". This is the only way you can test with your devices.
  7. You still need profiles for commercial or free distribution in the app store. You can also get these in the developer area from Apple.
  8. Develop your app in Xcode (you can also use additional frameworks to make your work easier). The language here is Objective C.
  9. Upload your app to the app store after you have entered the basic information of the app via the developer area.
  10. Wait for the app to be approved by Apple.
  11. Continue programming your app and respond to user reviews to generate further versions of the app.
