This section tells you a few things you need to know before you get started, such as what youll need for hardware and software, where to find the project files for this book and more.

To follow along with the tutorials in this book, youll need the following:

• A Mac running macOS Big Sur 11.6 or later. with the latest point release and security patches installed. This is so you can install the latest version of the required development tool: Xcode.

• Xcode 13 or later. Xcode is the main development tool for writing code in Swift. You need Xcode 13 at a minimum, since that version includes Swift 5.5 Xcode playgrounds. You can download the latest version of Xcode for free from the Mac App Store, here: apple.co/1FLn51R

If you havent installed the latest version of Xcode, be sure to do that before continuing with the book. The code covered in this book depends on Swift 5.5 and Xcode 13 you may get lost if you try to work with an older version or work outside the playground environment that this book assumes.
