Preface
We’ve been developing for the Cocoa framework from when the Mac first supported it. Since then, we’ve seen the ecosystem of Cocoa and Objective-C development evolve from a small programmer’s niche to one of the most important and influential development environments in the world. (In fact, as 2012 closes, Objective-C is the third most popular programming language according to the TIOBE index, up from fifth most popular in 2011.)
Over the years, we’ve built a lot of large, complex iOS and OS X software, shipping it to millions upon millions of users along the way. We’ve picked up a deep understanding of the toolset, frameworks, and programming language, an understanding crucial to building the best possible software for iOS and OS X. Apple constantly changes things, as the recent introduction of the svelte iPad mini and the stretched iPhone 5 show, but the knowledge necessary to bend the development tools, frameworks and languages to your will stays fairly constant. This book will give you the knowledge, confidence, and appreciation for iOS and OS X development with Cocoa, Cocoa Touch, and Objective-C.
Audience
We assume that you’re a reasonably capable programmer, but we don’t assume you’ve ever developed for iOS or OS X, or used Objective-C before. We also assume that you’re fairly comfortable navigating OS X as a user, and know how to use an iOS device.
