Hello! iOS Development is a book I co-wrote with Eitan Mendelowitz.
Manning’s Hello! series is aimed at combining a visual tutorial style with humor to make learning technical topics fun. The books are supplemented with User Friendly comics that have been adapted to relate to the topics in the book.
This book was written before Swift and for iOS 6. I don’t recommend you use this to learn iOS any more. If you are a beginner, checkout out my free companion to the Swift Programming Language book by Apple.
