Product Description
is the perfect jumpstart to the Swift language for every experienced Objective-C developer. Leading iOS and OS X developers Matt Henderson and Dave Wood help you take full advantage of Swifts powerful innovations, without wasting time on basics you already know.
Through expert code examples and crystal-clear explanations, Henderson and Wood reveal how Swift features improve on Objective-C and show how to make the most of them. Youll quickly master Swift-er techniques for using objects, classes, optionals, generics, functions, closures, and more. Each chapter includes hands-on exercises designed to reinforce and deepen your skills.
Youll learn how to re-implement common Objective-C programming solutions in Swift, improving code clarity, power, and performance on both desktop and mobile devices. And, because you probably wont (or cant) abandon Objective-C anytime soon, youll discover how to use both languages together, smoothly integrate Swift into existing projects and workflows, and gradually move your current code base into the future.
