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.

This application was pretty exciting at first, but the excitement of printing static text wore off pretty quickly. For my second application, I used BASIC's input command to prompt the user for a name and then printed out a custom hello message to the user with their name in it. At the age of 12, it was pretty cool to display Hello Han Solo. This application led me to create numerous Mad Lib style applications that prompted the user for various words and then put those words into a story that was displayed after the user had entered all the required words. These applications introduced me to, and taught me, the importance of variables. Every useful application that I created since then has used variables.

In this chapter, we will cover the following topics:
