Preface

Since Apple announced the Swift programming language at WWDC 2014, it has gone on to become one of the fastest growing programming languages. Swift is modern, open source, and easy to use, and therefore Swift's usefulness can extend beyond Apple's ecosystem, giving it the potential to be used across all platforms and for any scenario.

Swift 4 represents the latest version of this exciting new programming language, giving you the tools to build performant and responsive apps, with safe and clean code.

This book will guide you through Swift's features, building up your knowledge and toolset layer by layer, so you can use Swift to build the next great app or service.

You will be given useful, easy-to-follow recipes for using Swift to accomplish real-world tasks. Each recipe only uses concepts previously covered in the book, so you will never feel lost.

Learn what makes Swift one of the fastest growing and most exciting programming languages available today.
