Swift for the Really Impatient

Swift for the Really Impatient 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 Swift’s 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. You’ll 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.

You’ll 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 won’t (or can’t) abandon Objective-C anytime soon, you’ll 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. Coverage includes

Using Swift’s new patterns and concise, expressive syntax to produce safer, more reliable code
Leveraging the surprising power of Swift’s data structures
Utilizing Swift’s type system to help prevent errors common in other languages
Using optionals to correctly handle invalid, missing, or unknown values
Implementing generics to reduce duplication, improve power, and simplify maintenance
Interacting with C and Objective-C APIs
Abstracting functionality for reusable code while maintaining type safety
Isolating code in clean, flexible, low-overhead closures
Combining Swift with Objective-C in the same project
Avoiding gotchas when importing Objective-C classes in Swift projects
Nesting types to improve code clarity
Creating shared objects with singletons
Managing threading and concurrency with Swift’s advanced Grand Central Dispatch (GCD) patterns

Matt Henderson has been developing for Apple's platforms since 2009 and is currently a Cocoa Engineer at MartianCraft. He's given several presentations at various user groups and conferences, including 360iDev, Cocoaheads Denver, and Boulder iOS Meetup. His previous experience includes leading teams on both iOS and Android projects and developing in languages ranging from Java to embedded C/C++.

Dave Wood has been developing for iOS since 2008 and OS X since 2009. His experience includes developing systems that interface with stock exchanges, news outlets, and banking systems; creating newspaper sites; and building mobile apps of all kinds, from games and social networks to apps for finance, productivity, and professional development.
