iPhone Developer Program

2. Test on your iPhone

Develop directly on iPhone or iPod touch. Build, test, and optimize your application to get the best performance possible—exactly as your customers will experience it.

Test in Real-Time

Plug in your iPhone to use Xcode's graphical debugger, or collect real-time performance data in Instruments' timeline view. These powerful optimization tools allow you to quickly identify and address any performance issues.

Test Over the Air

With your application running on your iPhone and iPod touch, you can test the performance of your application connected to a Wi-Fi or carrier's network for a real world user experience.

Technical Support

The iPhone Developer Program includes two Technical Support Incidents where Apple engineers will provide you with code-level assistance, helpful guidance, or point you towards the appropriate technical documentation to fastrack your development process.

Free iPhone SDK

Start your development with the latest version of the iPhone SDK with Xcode IDE and iPhone simulator which includes OpenGL ES support, Interface Builder, Instruments, frameworks, samples, compilers, and the Shark analysis tool. Learn more
