子标题：Create funky, impressive applications using Swift
When Apple announced Swift at the WWDC, the iOS developer community became excited about the opportunities to improve the way in which they build iOS apps. Swift is a user-friendly language with a smooth learning curve; it is safe, robust, and flexible, and it introduces new ways to solve old problems.
Swift by Example is a fast-paced, practical guide that shows you how to develop iOS apps using Swift. Through the development of six different apps, you’ll learn how to use either the right feature of the language or the right tool to solve a given problem.
By the end of the book you will be able to build well-designed apps, effectively use AutoLayout, and develop a video game.
