Swift 2 Cookbook

Book Description:

Swift is Apple’s innovative development language that was introduced at the WWDC (WorldWide Developers Conference) 2014 alongside Xcode 6 and iOS 8. This user-friendly language is packed with modern features to make programming easier and fun, with a lot of flexibility. With Swift 2 comes even better performance, a new error handling API, protocol extensions, and super support for availability checking.

This book will equip you with all the practical programming aspects of Swift 2. It covers the important features and paradigms that Swift provides to developers. You will begin by installing Xcode from the App Store and using Swift as an interpreter. Then, you will see how you can upgrade your existing Swift 1.2 code to Swift 2.0 with the help of Xcode. You will see how to use structs and generics, and work with different Design Patterns with Swift. Debug and test your code using Xcode and see how to use assembly code effectively with Swift.

By the end of this book, you will have the necessary skills to get the most out of Swift to develop effective mobile and web applications.
