WWDC26: Use SwiftUI with AppKit and UIKit | Apple
Apple's WWDC26 session shows how to incrementally adopt SwiftUI inside existing AppKit and UIKit apps.
“Swift UI was designed from the beginning to work great alongside AppKit and UIKit, just like Swift was designed to work together with Objective C.”
A WWDC26 technical session walks developers through incrementally adopting SwiftUI within existing AppKit/UIKit apps, including observable macros, gesture recognizers, menu items, and scenes. It is a UI-framework engineering tutorial with no meaningful AI industry signal beyond a passing mention of Xcode's coding assistant.
