Learn how to develop great iPhone and iPad apps
Jack has been developing with Objective-C since the olden days, before Cocoa was even called Cocoa. He spends most of his time working on iOS projects, and has also spent a few years in the trenches working on Rails applications. He's also managed to find time to write a few books on iOS and Mac development in the past few years. In the few moments when he's not coding or thinking about coding, Jack enjoys spending time with his family, playing guitar, and working on game projects.
