In Detail

Over recent years, the market for mobile game development using Unity has grown multi-fold with an overwhelming 600 million gamers playing games developed using Unity engine. The newly launched Unity 5 offers a wide range of dedicated and powerful tools for iOS developers who intend to follow the basics and gradually elevate their skills to revolutionize the way they design and publish games for the App Store.

Moving on, you'll discover how to create development and release builds, enabling you to test the game on your device before finally submitting the game for Apple's approval.

By the end of the book, you will have a complete understanding of how iTunes and Unity can be used in combination to build and publish a fully interactive and reliable game to the App Store.
