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.

Introducing our server project


Let's go out with a bang! For this last chapter, we are going to create a small project to test developing a server app in Swift. We will use the IBM Swift Package Catalog to find a web server framework. I really like using Slack for team communication. If you haven't tried it, you should consider evaluating whether it could be a good tool for your team. One of the powerful features of Slack is the array of integration options you have to customize the experience for your team. Slack has opened many of its APIs to developers for customization and integration. Slack even provides an App Store for users to add third-party apps that their teams can use together. The catch, if there is one, is that your third-party app or integration has to be hosted on an outside server. We are going to create a Slack integration that you can later modify into a full Slack app of your own. Our Slack integration will be written entirely in Swift, and it could be hosted on a Linux...
