The iOS 8 SDK offers powerful new features, and this book is the fastest path to mastering them—and the rest of the iOS SDK —for programmers with some experience who are new to iPhone and iPad app development. Many books introduce the iOS SDK, but few explain how to develop apps optimally and soundly. This book teaches both core Swift language concepts and how to exploit design patterns and logic with the iOS SDK, based on Swift and the Cocoa Touch framework. Why spend months or years discovering the best ways to design and code iPhone and iPad apps when this book will show you how to do things the right way from the start?
