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.

Behavioral design patterns


Behavioral design patterns explain how types interact with each other. These patterns describe how different instances of types send messages to each other to make things happen.

There are nine well-known patterns that are part of the behavioral design pattern type. They are as follows:

  • Chain of responsibility: This is used to process a variety of requests, each of which may be delegated to a different handler.

  • Command: This creates objects that can encapsulate actions or parameters so that they can be invoked later or by a different component.

  • Iterator: This allows us to access the elements of an object sequentially without exposing the underlying structure.

  • Mediator: This is used to reduce coupling between types that communicate with each other.

  • Memento: This is used to capture the current state of an object and store it in a manner that can be restored later.

  • Observer: This allows an object to publish changes to its state. Other objects can then subscribe so...
