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.

Swift 3 on Linux


The Swift team currently supports installing Linux on Ubuntu 14.04 or 15.10 (64-bit). On Linux, Swift packages are distributed as tar archives. Each package includes the Swift compiler, the LLDB debugger, and tools related to doing development in Swift.

Note

If you don't have access to a Linux box, you can create a virtual machine using VirtualBox https://www.virtualbox.org and Vagrant https://www.vagrantup.com.

VirtualBox is a virtualization application that runs on multiple platforms and allows you to install another OS. You can download the latest version from https://www.virtualbox.org/wiki/Downloads.

Vagrant is a configuration and provisioning package that allows you to install and configure a complete development environment. You can find instructions on how to install and configure a Linux box at this location https://www.vagrantup.com/
