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 14. Concurrency and Parallelism in Swift

When I first started learning Objective-C, I already had a good understanding of concurrency and multitasking with my background in other languages, such as C and Java. This background made it very easy for me to create multithreaded applications using threads in Objective-C. Then, Apple changed everything when they released Grand Central Dispatch (GCD) with OS X 10.6 and iOS 4. At first, I went into denial: there was no way GCD could manage my application's threads better than I could. Then I entered the anger phase: GCD was hard to use and understand. Next was the bargaining phase: maybe I can use GCD with my threading code, so I could still control how the threading worked. Then there was the depression phase: maybe GCD does handle threading better than I can. Finally, I entered the wow phase: this GCD thing is really easy to use and works amazingly well. After using GCD on Apple platforms for so long, I was very happy to hear that Apple...
