The students learn this by studying the thousands of lines of fully vetted Swift program code that comes with the book.
- A programming-language focused book designed to get practicing programmers up-to-speed quickly in Swift programming
- Learn the new programming language for iOS and OS X apps that builds on the best of C and Objective-C
- Includes code snippets and live-code examples
The professional programmer's Deitel(R) guide to Apple's new Swift programming language for the iOS(R) and OS X(R) platforms: Written for programmers with a background in object-oriented programming in a C-based language like Objective-C, Java, C# or C++, this book applies the Deitel signature live-code approach with scores of complete, working, real-world programs to explore the new Swift language in depth.
The code examples feature syntax shading, code highlighting, rich commenting, line-by-line code walkthroughs and live program outputs. The book features thousands of lines of proven Swift code, and tips that will help you build robust applications.
Start with an introduction to Swift using an early classes and objects approach, then rapidly move on to more advanced topics. When you master the material, you'll be ready to build industrial-strength object-oriented Swift applications.
About This Book The Swift(TM) programming language was arguably the most significant announcement at Apple's 2014 Worldwide Developers Conference.
Although apps can still be developed in Objective-C(R), Apple says that Swift is its applications programming and systems programming language of the future. Swift is a contemporary language with simpler syntax than Objective-C. Because Swift is new, its designers were able to include popular programming language features from languages such as Objective-C, Java(TM), C#, Ruby, Python(R) and many others.
These features include automatic reference counting (ARC), type inference, optionals, String interpolation, tuples, closures (lambdas), extensions, generics, operator overloading, functions with multiple return values, switch statement enhancements and more. We've been able to develop apps more quickly in Swift than with Objective-C and the code is shorter, clearer and runs faster on today's multi-core architectures.
Swift also eliminates the possibility of many errors common in other languages, making your code more robust and secure.
Some of these error-prevention features include no implicit conversions, ARC, no pointers, required braces around every control statement's body, assignment operators that do not return values, requiring initialization of all variables and constants before they're used, array bounds checking, automatic checking for overflow of integer calculations, and more. You can combine Swift and Objective-C in the same app to enhance existing Objective-C apps without having to rewrite all the code.
Your apps will easily be able to interact with the Cocoa(R)/Cocoa Touch(R) frameworks, which are largely written in Objective-C. You can also use the new Xcode playgrounds with Swift. A playground is an Xcode window in which you can enter Swift code that compiles and executes as you type it.
This allows you to see and hear your code's results as you write it, quickly find and fix errors, and conveniently experiment with features of Swift and the Cocoa/Cocoa Touch frameworks.

Apple took everyone by surprise when they announced a new programming language for developing Mac and iOS applications. Taking lessons from Objective-C and many other languages, Apple built a new language from the ground up. There is a lot to learn–new syntax, new idioms and more. It all seems daunting, but the Deitels have written a book that thoroughly explores Swift and Xcode 6 and guides you through what you need to know, regardless of which language you came from.
Robert McGovern, Independent Developer
It’s surprising that a book of this quality, depth and breadth has appeared so soon after Swift was announced. The ideal accompaniment to Apple’s reference documentation. This developers’ book takes an in-depth look at Swift. Whether you’re moving to the Apple ecosystem from a C++, C# or Java background or you’re an Objective-C programmer looking to update your skills to this newest and most exciting of Apple’s languages, this book is for you. Complements the Deitels’ excellent book iOS 8 for Programmers: An App-Driven Approach with Swift and maintains their trademark high-quality approach, containing many interactive, nontrivial code examples with in-depth code walkthroughs and best practices. Uses the power of Swift with Cocoa’s Foundation classes. A must-have for any serious Apple developer.
Rik Watson, Technical Team Lead for HP Enterprise Services (Applications Services)
An excellent introduction to Apple’s new programming language. Line-by-line code explanations. Practical real-world abstractions throughout the code. Full of links to great resources. Features are introduced by comparison to established programming concepts making Swift easy to learn for developers new to Apple’s platforms. A must-read.
