Mastering Swift 3

Overview of this book

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 3.0, the Swift team have 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 3.0 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 even the most challenging design patterns and programming techniques can be used to write cleaner code and to build more performant iOS and OS X applications. By the end of this book, you’ll have a handle on effective design patterns and techniques, which means you’ll soon be writing better iOS and OS X applications with a new level of sophistication and control.

Summary


As this chapter ends, we end the introduction to the Swift programming language. At this point, we have enough knowledge of the Swift language to begin writing our own applications; however, there is still much to learn.

In the following chapters, we will look in more depth at some of the concepts that we already discussed, such as optionals and subscripts. We will also show how to perform common tasks with Swift, such as parsing common file formats and handling concurrency. Finally, we will have some chapters that will help us write better code, such as a sample Swift style guide, and a chapter on design patterns.
