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.

Chapter 16. Swifts Core Libraries

I was really excited when Apple announced that they were going to release a version of Swift for Linux, so I could use Swift for my Linux and embedded development as well as my Mac OS and iOS development. When Apple first released Swift 2.2 for Linux, I was very excited but I was also a little disappointed because I could not read/write files, access network services, or use libdispatch (GCD) on Linux like I could on Apple's platforms. With the release of Swift 3, Apple has corrected this with the release of Swift's core libraries.

In this chapter, you will learn about the following topics:

  • What are the Swift Core Libraries?

  • How to use Apple's URL loading system?

  • How to use the Formatter classes?

  • How to use the FileManager class?

  • How to serialize and deserialize JSON data?

The Swift Core Libraries are written to provide a rich set of APIs that are consistent across the various platforms that Swift supports. By using these libraries, developers will be able to write...
