The success behind the phenomenal growth of these devices lies in the applications bundled with them, which increases their functionality exponentially.

We will learn how to develop iOS applications with RubyMotion by building sample applications from scratch. We will try to have something tangible with a running code by the end of every chapter so that you can see a clear progression from chapter to chapter.
