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.

Creational patterns


Creational patterns are design patterns that deal with how an object is created. These patterns create objects in a manner suitable for particular situations.

There are two basic ideas behind creational patterns. The first is encapsulating the knowledge of which concrete types should be created, and the second is hiding how the instances of these types are created.

The following are the five well-known patterns that are a part of the creational pattern category:

  • Abstract factory pattern: This provides an interface for creating related objects without specifying the concrete type

  • Builder pattern: This separates the construction of a complex object from its representation, so the same process can be used to create similar types

  • Factory method pattern: This creates objects without exposing the underlying logic of how the object (or which type of object) is created

  • Prototype pattern: This creates an object by cloning an existing one

  • Singleton pattern: This allows one (and only...
