Discover how to incrementally adopt SwiftUI in your existing AppKit or UIKit app. We’ll show you how to use the Observation framework to automatically update your views, integrate SwiftUI components into an existing view hierarchy, and bring gesture recognizers into SwiftUI. We’ll also explore how to add complete SwiftUI scenes to your app without changing your overall architecture.
