To follow along with this book, you’ll need the following:
- A Mac running macOS Ventura (13.0) or later. Earlier versions might work, but they’re untested.
- Xcode 14 or later. Xcode is the main development tool for iOS. While earlier versions of Xcode should work, the examples in this book have been specifically tested on Xcode 14 and iOS 16. You can download the latest version of Xcode from Apple’s developer site here: apple.co/2asi58y
- An intermediate level knowledge of Swift. This book teaches concurrency when building iOS applications using Swift. You could use the knowledge acquired in this book for your Objective-C codebase, but this book won’t include any Objective-C examples. You could also use this knowledge for your macOS, tvOS and watchOS apps, but like Objective-C, this book won’t include any examples for these platforms.
If you want to try things out on a physical iOS device, you’ll need a developer account with Apple, which you can obtain for free. However, all the sample projects in this book will work just fine in the iOS Simulator bundled with Xcode, so the paid developer account is completely optional.
