Adam Preble

Aaron Hillegass, a former employee at NeXT and Apple, has nearly two decades experience programming and teaching Objective-C, Cocoa, and, more recently, iOS. Aaron is co-author of Objective-C Programming: The Big Nerd Ranch Guide and iOS Programming: The Big Nerd Ranch Guide. In 2001, Aaron founded Big Nerd Ranch and began developing intensive courses that teach programming in a focused, distraction-free environment. Big Nerd Ranch now offers courses around the world as well as consulting and software development.

Adam Preble learned Cocoa programming from the first edition of this book and after ten years in the software industry, joined Big Nerd Ranch to write Mac and iOS software as a consultant. He presently leads engineering at Big Nerd Ranch and steals away time for Cocoa programming and for teaching the Cocoa bootcamp course, on which this book is based.

Nate Chandler is an instructor and senior software engineer at Big Nerd Ranch, where he helps maintain the Cocoa bootcamp course materials. Nate studied mathematics at the New College of Florida and applies the logical rigor he learned in that arena to his programming. An avid C++ enthusiast, Nate reads draft feature proposals for the standard as often as he can.
