Mastering Swift 3 - Linux

By: Jon Hoffman

Overview of this book

Swift is a modern, fast, and safe programming language created by Apple. Writing Swift is interactive and fun, the syntax is concise yet expressive, and the code runs lightning-fast. Swift’s move to open source has been embraced with open arms and has seen increased adoption in the Linux platform. Our book will introduce you to the Swift language, further delving into all the key concepts you need to create applications for desktop, server, and embedded Linux platforms. We will teach you the best practices to design an application with Swift 3 via design patterns and Protocol-Oriented Programming. Further on, you will learn how to catch and respond to errors within your application. When you have gained a strong knowledge of using Swift in Linux, we’ll show you how to build IoT and robotic projects using Swift on single board computers. By the end of the book, you will have a solid understanding of the Swift Language with Linux and will be able to create your own applications with ease.

Chapter 4. Control Flow and Functions

While I was learning BASIC programming on my Vic-20, every month I would read several of the early computer magazines such as Byte Magazine. I remember one particular review that I read; it was for a game called Zork. While Zork was not a game that was available for my Vic-20, the concept of the game fascinated me because I was really into Sci-Fi and fantasy. I remember thinking how cool it would be to write a game like that, so I decided to figure out how to do it. One of the biggest concepts that I had to grasp at that time was controlling the flow of the application depending on the user's actions.

In this chapter, we will cover the following topics:

  • What are conditional statements and how to use them

  • What are loops and how to use them

  • What are control transfer statements and how to use them

  • How to create and use functions in Swift
