Objective-C the language of choice for iOS and OS X development, is a decades-old language built upon the C language. It's powerful and dynamic nature allow you to write incredible software, and it's C underpinnings allow you to write performance-heavy code as well. Advanced Objective-C takes you on a tour for Objective-C's inner workings. You'll learn the details about how Objective-C really works, how to use runtime features like dynamically created classes, and how to work with JSON-created objects. You'll also learn compiler shortcuts, and you'll get the inside picture on what's happening in ARC. Finally, you learn about class clusters, using SQLite-backed NSArray, and how to write truly safe Objective-C code. Pro Objective-C breaks your understanding of the language down into its component parts and then reassembles them into powerful knowledge that unlocks your ability to write better, faster, and safer code.
