Swift 3 New Features

By: Keith Elliott

Overview of this book

Since Swift was introduced by Apple in WWDC 2015, it has gone on to become one of the most beloved languages to develop iOS applications with. In the new version, the Swift team aimed to take its adoption to the next level by making it available for new platforms and audiences. This book will very quickly get you up to speed and productive with Swift 3. You will begin by understanding the process of submitting new feature requests for future versions of Swift. Swift 3 allows you to develop and run your applications on a Linux machine. Using this feature, you will write your first Linux application using the debugger in Linux. Using Swift migrator, you will initiate a conversion from Swift 2.2 to Swift 3. Further on, you will learn how to interact with Cocoa libraries when importing Objective C to Swift. You will explore the function and operator changes new to Swift 3, followed by Collection and Closure changes. You will also see the changes in Swift 3 that allow you write tests easier with XCTest and debug your running code better with new formats as well. Finally, you will have a running server written completely in Swift on a Linux box. By the end of the book, you will know everything you need to know to dive into Swift 3 and build successful projects.

Summary


In this chapter, we explored Swift on the server. We developed a web application that runs entirely in Swift. Our application also communicates with Slack to post messages. We used the Vapor web framework to create a Swift web server, and you learned how to call Slack webhooks from Swift. While our example was fairly simple, it is easy to see how we could expand it to a larger and more complex application leveraging the power of Swift.

This brings us to the end of the book. We've covered a lot of material and learned the new features of Swift 3. We discussed Apple's motivation and objectives for the evolution of Swift. I have shown you where to find documentation on the language and how to get involved with the future direction of Swift. We explored Swift on Linux and some of the possibilities this creates for server-side Swift applications. Swift 3 adds new language features that improve many of the libraries that you will use everyday in your coding projects.

It's my hope that this...
