What You Need
To follow along with this book, you’ll need the following:
- Xcode 11 or later. Xcode is the main development tool for writing code in Swift. You need Xcode 11 at a minimum, since that version includes Swift 5.1. You can download the latest version of Xcode for free from the Mac App Store, here: apple.co/1FLn51R.
If you haven’t 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 5.1 and Xcode 11 — the code may not compile if you try to work with an older version.
