Who This Book Is For

If you are an Apple developer who wants to use Swift to build your applications, this book is for you. With Swift 2 going open source, this book will also help web developers. Some understanding of Objective-C or Swift would be helpful but is not required.

What You Will Learn

• Install Xcode from the App Store
• Upgrade your existing Swift 1.2 code to Swift 2.0
• Use the standard Swift 2.0 library and collections
• Work with structs, generics, and design patterns in Swift
• Use the new markup language to provide rich documentation of code
• Write a book using Playgrounds and Swift
• Debug and test your code using Xcode
• Integrate your code with Objective-C and use assembly code with Swift
• Leverage the Objective-C runtime when compiling Swift using associated objects

In Detail

Swift is Apple's innovative development language that was introduced at the WWDC (WorldWide Developers Conference) 2014 alongside Xcode 6 and iOS 8. This user-friendly language is packed with modern features to make programming easier and fun, with a lot of flexibility. With Swift 2 comes even better performance, a new error handling API, protocol extensions, and super support for availability checking.

This book will equip you with all the practical programming aspects of Swift 2. It covers the important features and paradigms that Swift provides to developers. You will begin by installing Xcode from the App Store and using Swift as an interpreter. Then, you will see how you can upgrade your existing Swift 1.2 code to Swift 2.0 with the help of Xcode. You will see how to use structs and generics, and work with different Design Patterns with Swift. Debug and test your code using Xcode and see how to use assembly code effectively with Swift.

By the end of this book, you will have the necessary skills to get the most out of Swift to develop effective mobile and web applications.
