To get the most out of this book
You need the latest version of Xcode installed on your Mac. The code in this book has been tested with Xcode 13 and Swift 5.5 but it should also work with newer versions of Xcode and Swift.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
You should try to do all the exercises in the book. They are designed to give you more insight and strengthen your experience.
