Get up to speed on Cocoa and Objective-C, and start developing applications on the iOS and OS X platforms. If you don't have experience with Apple's developer tools, no problem! From object-oriented programming to storing app data in iCloud, the fourth edition of this book covers everything you need to build apps for the iPhone, iPad, and Mac.
Paris Buttfield-Addison is a mobile app engineer, game designer and researcher with a passion for making technology simpler and as engaging as possible. He has written two books on game development and currently spends his time designing mobile products for millions upon millions of users while drinking too much coffee. Paris has coded for everything from Qt to 6502 assembly to iOS and thinks digital watches are a pretty neat idea. He claims he will soon have a PhD. Jon Manning is an iOS development guru, writer and teacher. Previously an author for the For Dummies series, he has written apps for millions of people and frequently finds himself accidentally teaching iOS development. Tim Nugent pretends to be a mobile app developer, game designer, PhD student, and now he even pretends to be an author. When he isn't busy avoiding being found out as a fraud, he spends most of his time designing and creating little apps and games he won't let anyone see. Tim spent a disproportionately long time writing this tiny little bio, most of which was spent trying to stick a witty sci-fi reference in, before he simply gave up. Tim can be found as @The_McJones on Twitter
