Swift is a general-purpose programming language that takes a modern approach to development. It was first introduced by Apple at the Worldwide Developers Conference (WWDC) in 2014. Five years later, they released version 5 of Swift.

Swift 5 offers many enhancements and improvements to the Swift language with the biggest being ABI stability. Some of the other improvements are the ability to create raw strings, handling of future enum cases, and added isMultiple(of:) to integers just to name a few.

This book is for the developer who wants to dive into the newest version of Swift. If you are a developer that learns best by looking at, and working with code, then this book is for you. A basic understanding of Apples tools is beneficial but not mandatory.

, Taking the First Steps with Swift, will introduce you to the Swift programming language and discuss what inspired Apple to create Swift. We'll also go over the basic syntax of Swift and how to use Playgrounds to experiment and test Swift code.

, Learning about Variables, Constants, Strings and Operators will introduce you to variables and constants in Swift and when to use them. There will be brief overviews of the most common variable types with examples on how to use them. This chapter concludes by showing examples of how to use the most common operators in the Swift language.
