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.

What are design patterns?


Every experienced developer has a set of informal strategies that shape how he or she designs and writes applications. These strategies are shaped by the experiences of developers and the obstacles they have had to overcome in previous projects. While these developers might swear by their own strategies, it does not mean that their strategies have been fully vetted. The use of these strategies can also introduce inconsistent implementations among different projects and developers.

While the concept of design patterns dates back to the mid 80s, they did not gain popularity until the Gang of Four released their book Design Patterns: Elements of Reusable Object-Oriented Software, published in 1994. The book's authors, Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (also known as the Gang of Four), discuss the pitfalls of object-oriented programming and describe 23 classic software design patterns. These 23 patterns are broken up into three categories:...
