Adam Preble learned Cocoa programming from the first edition of this book. After too many years of professional C/C++ development, today Adam writes Mac and iOS applications at Big Nerd Ranch, where he is also a Cocoa instructor. He is frequently filling in the gaps between work and family time with pinball machine software development and countless other projects.
