To use NSViewRepresentable to wrap an AppKit view in SwiftUI, you implement the wrapper protocol to expose existing NSView components within SwiftUI views. This pattern enables incremental adoption by embedding AppKit elements like NSTextView directly into SwiftUI layouts.

The best way to embed SwiftUI views inside an existing AppKit application is using NSHostingView or NSHostingController. These hosting containers allow you to introduce SwiftUI components gradually into NSView and NSViewController hierarchies.

To synchronize state between AppKit and SwiftUI frameworks, you implement shared state strategies using @Observable or Combine. This ensures cross-framework communication and consistent state management during incremental adoption.

Incremental adoption of SwiftUI in AppKit requires explicit lifecycle management. Bridging these frameworks necessitates careful handling of view lifecycles, layout constraints, and state synchronization to maintain performance.

You can gradually introduce SwiftUI into a legacy macOS AppKit app by bridging the two frameworks. This approach uses NSHostingView for embedding SwiftUI and NSViewRepresentable for wrapping AppKit views, enabling cross-framework collaboration without a full rewrite.

Your SwiftUI interface may lag when bridging complex AppKit components due to inefficient state synchronization or layout issues. Addressing performance requires applying explicit lifecycle management and shared state strategies across frameworks.
