Book Description

Swift is the definitive language of Apple development today. It's a vital part of any iOS and OS X developer's skillset, helping them to build the most impressive and popular apps on the App Store-the sort of apps that are essential to iPhone and iPad users every day. With version 4.0, the Swift team has added new features to improve the development experience-making it easier to get the results you want and customers expect.

Inside, you'll find the key features of Swift 4.0 and quickly learn how to use the newest updates to your development advantage. From Objective-C interoperability to ARC, to closures and concurrency, this advanced Swift guide will develop your expertise and make you more fluent in this vital programming language.

We give you in-depth knowledge of some of the most sophisticated elements of Swift development including protocol extensions, error-handling, design patterns, and concurrency, and guide you on how to use and apply them in your own projects. You'll see how to leverage the power of Protocol-Oriented program to write cleaner and easier to manage code. We will also show you how Apple uses Protocol-Oriented programming techniques in the Swift standard library.
