SwiftUI works seamlessly with the existing UI frameworks on all Apple platforms. For example, you can place UIKit views and view controllers inside SwiftUI views, and vice versa.
This tutorial shows you how to convert the featured landmark from the home screen to wrap instances of
UIPageViewControllerandUIPageControl. You’ll useUIPageViewControllerto display a carousel of SwiftUI views, and use state variables and bindings to coordinate data updates throughout the user interface.Follow the steps to build this project, or download the finished project to explore on your own.
