In 2012 I created a How to Build an App in 5 Days course that I taught to International students at Silicon Beach Training in Brighton.
I was later contacted by Apress and invited to turn my course into a book. In Foundation iPhone App Development I teach a hands-on process to learning Objective-C and the iOS SDK through the development of a professional iPhone app from start to finish.
You can check out my book and read some of the lovely reviews it received on Amazon here.
