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 is a programming style guide?


Coding styles are very personal and every developer has his or her own preferred style. These styles can vary from language to language, person to person, and also change over time. The personal nature of coding styles can make it difficult to have a consistent and readable code base when numerous individuals are contributing to the code.

While most developers might have their own preferred styles, the recommended or preferred style between languages can vary. As an example, in C#, when we name a method or function, it is preferred to use camel case with the first letter being capitalized. While in most other languages, such as C, Objective-C, and Java, it is also recommended that we use camel case, but it is recommended that we make the first letter lower case.

The best applications are coded properly, and by properly we do not just mean that they function correctly but also that they are easy to maintain and the code is easy to read. It is hard for large...
