Learning Swift Programming Paperback

Get started fast with Swift programming for iOS and OS X

Learning Swift Programming is a fast-paced, hands-on introduction to writing production-quality iOS and OS X apps with Apple’s new programming language. Written for developers with previous experience in any other modern language, this book explains Swift simply and clearly, using relevant examples that solve realistic problems.

Author Jacob Schatz’s popular Skip Wilson video tutorials on YouTube have already helped thousands of Apple developers get started with Swift. Now, he helps you take full advantage of Swift’s advanced design, remarkable performance, and streamlined development techniques.

Step-by-step, you’ll move from basic syntax through advanced features such as closures and generics–discovering helpful tips and tricks along the way. After you’ve mastered Swift’s building blocks and learned about its key innovations, a full section of case studies walks you through building complete apps from scratch.

• Compare Swift with Objective-C, JavaScript, Python, Ruby, and C
• Collect data with arrays and dictionaries, and store it with variables and constants
• Group commonly-used code into functions for easy reuse
• Structure your code with enums, structs, and classes
• Use generics to get more done with less code
• Write closures to share small blocks of functionality
• Use optionals to write more robust, crash-resistant, and cleaner code
• Integrate existing Objective-C code into new Swift apps
• Program on the bit and byte level with advanced operators
• Implement efficient design patterns with protocols and delegates
• Create animated 2D games with SpriteKit, and 3D games with SceneKit

快速入門Swift程式設計，針對iOS和OS X。《學習Swift程式設計》是一本快節奏、實踐性強的介紹，教你如何使用蘋果的新程式語言撰寫高品質的iOS和OS X應用程式。本書針對已具備其他現代程式語言經驗的開發者，以簡單明瞭的方式解釋Swift，並提供解決實際問題的相關範例。

作者Jacob Schatz在YouTube上的熱門Skip Wilson視頻教程已幫助數千名蘋果開發者入門Swift。現在，他將幫助你充分利用Swift的先進設計、卓越性能和簡化開發技術。

逐步進行，從基本語法到閉包和泛型等高級功能，並在此過程中發現有用的技巧和訣竅。在掌握了Swift的基礎結構和關鍵創新後，一整節的案例研究將引導你從頭開始建立完整的應用程式。

• 比較Swift與Objective-C、JavaScript、Python、Ruby和C


• 使用陣列和字典收集資料，並使用變數和常數儲存資料


• 將常用程式碼分組為函式以便輕鬆重複使用


• 使用列舉、結構和類別組織程式碼


• 使用泛型以更少的程式碼完成更多工作


• 撰寫閉包以共享小塊功能


• 使用可選型撰寫更健壯、防止崩潰且更乾淨的程式碼


• 將現有的Objective-C程式碼整合到新的Swift應用程式中


• 使用高級運算子在位元和位元組級別進行程式設計


• 使用協議和委派實現高效的設計模式


• 使用SpriteKit創建2D動畫遊戲，使用SceneKit創建3D遊戲
