SwiftUI iOS 18 Tour

Getting Started

Use this companion app to tour the major additions to the SwiftUI framework which were added in iOS 18. Just clone or download this repo, and then open the Xcode project. From there, you can either run the app on your phone to reference it whenever you need, or you can view the entire experience using Xcode Previews. Either way!

This project requires Xcode 16 or later.
