Swift 2 By Example

Overview of this book

Swift is no longer the unripe language it was when launched by Apple at WWDC14, now it’s a powerful and ready-for-production programming language that has empowered most new released apps. Swift is a user-friendly language with a smooth learning curve; it is safe, robust, and really flexible. Swift 2 is more powerful than ever; it introduces new ways to solve old problems, more robust error handling, and a new programming paradigm that favours composition over inheritance. Swift 2 by Example is a fast-paced, practical guide to help you learn how to develop iOS apps using Swift. Through the development of seven different iOS apps and one server app, you’ll find out how to use either the right feature of the language or the right tool to solve a given problem. We begin by introducing you to the latest features of Swift 2, further kick-starting your app development journey by building a guessing game app, followed by a memory game. It doesn’t end there, with a few more apps in store for you: a to-do list, a beautiful weather app, two games: Flappy Swift and Cube Runner, and finally an ecommerce app to top everything off. By the end of the book, you’ll be able to build well-designed apps, effectively use AutoLayout, develop videogames, and build server apps.

One skeleton server for two OSes


Before implementing the server, we need to prepare a build environment for both OS X and Linux; also, let's prepare a HelloWorld server, which handles a GET and POST request in a predefined URL.

An OS X skeleton server

The Swift open source version for OS X can be downloaded from https://swift.org/download/#latest-development-snapshots; however, because a new version is released every week, it could be too complicated to be aligned with the version.

Preparing the OS X environment

Fortunately, taking inspiration from projects in different languages, such as PyEnv for Python, Kyle Fuller released a useful version manager for Swift called Swift Version Manager, which can install and manage different versions of Swift on the same machine, optionally tying a particular version of the language for each project.

The GitHub page of the project, https://github.com/kylef/swiftenv, shows different ways to install it, although I suggest that you do it via Homebrew using this...
