Technical requirements
We will walk you through setting up Xcode 15.0 and use this development environment unless otherwise stated. Xcode 15.0 can be downloaded from the Apple App Store on a Mac running the latest OS.
We will be using Swift 5.9. This version will also be more compatible with future versions of Swift, which means that code written now with Swift 5.9 can run alongside code written with future versions of Swift.
We will be using Playgrounds in Xcode to implement the recipes contained in this book unless otherwise stated. The benefit of using Xcode Playgrounds is its simplicity of quickly writing and compiling Swift syntax.
All the code for this chapter can be found in the book’s GitHub repository at https://github.com/PacktPublishing/Swift-Cookbook-Third-Edition/tree/main/Chapter%201.
