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 11. Working with Generics

My first experience with generics was back in 2004, when they were first introduced in the Java programming language. I can still remember picking up my copy of The Java Programming Language, Fourth Edition, which covered Java 5, and reading about Java's implementation of generics. Since then, I have used generics in a number of projects, not only in Java but in other languages as well. If you are familiar with generics in other languages, such as Java, the syntax that Swift uses will be familiar to you. Generics allow us to write very flexible and reusable code; however, just as with subscripts, we need to make sure that we use them properly and do not overuse them.

In this chapter, we will cover the following topics:

  • An introduction to generics

  • Creating and using generic functions

  • Creating and using generic classes

  • Using associated types with protocols
