This book is divided into two sections. The first section provides an introduction to the Swift programming language and covers many of the more practical topics you will encounter as a Swift programmer. The second section is a “deep dive” into the intricacies of Swift.
This part of the book teaches the Swift language, from the ground up. The description is rigorous and orderly. Here you’ll become sufficiently conversant with Swift to be comfortable with it, so that you can proceed to the practical business of actual programming.

Swift by Tutorials。At WWDC 2014, Apple introduced the shiny, new Swift language. Swift brings concise syntax, type safety and modern programming language features to Mac and iOS developers. The Apple developer community has responded with great excitement and adoption is growing rapidly. <br> From OS X to iOS, from Macs to iPhones to watches, and from command-line scripts to playgrounds — Swift is the way of the future for developing on Apple’s platforms. <br> This book focuses on using Swift to write iOS applications. However, the language fundamentals you’ll learn are also applicable to development on any other Swift platform.

With iOS 9 SDK during WWDC 2015, Apple introduced some very big changes, including the introduction of watchOS 2 which really changed how we interact, as programmers, with the ?Watch. Previously, almost all requests had to go to the companion iOS device from the watch and then served by the iOS app. With watchOS 2, the watch takes a lot more responsibilities and can update its content almost always by itself.<br> Among the new tools in iOS 9, there is a new UI Testing framework and the ability to write UI tests purely in Swift. iOS 9 Swift Programming Cookbook has a whole chapter dedicated to this subject so that you can get started with UI Testing in no time.
Swift is the easiest way to get started developing on Apple’s platforms: iOS, OS X, watchOS and tvOS. With the release of Swift 2 in 2015, the Swift language is packed with even more features and enhancements.<br> In this book, you’ll learn the basics of Swift from getting started with playgrounds to simple operations to building your own types. Everything you’ll learn is platform-neutral; you’ll have a firm understanding of Swift by the end of this book, and you’ll be ready to move on to whichever app platform you’re interested in.
Swift brings with it many modern language features, including type safety, generics, type inference, closures, tuples, protocols, automatic memory management, and support for Unicode (for character and string values as well as for identifiers). You can use a mixture of Swift and Objective-C in a single project, and either language can call APIs implemented in the other.
