AppKit Interop

Quick Start

Use this skill when SwiftUI is close but not quite enough for native macOS behavior. Keep the bridge as small and explicit as possible. SwiftUI should usually remain the source of truth, while AppKit handles the imperative edge.

Choose The Smallest Bridge

• Use pure SwiftUI when the required behavior already exists in scenes, toolbars, commands, inspectors, or standard controls.
• Use NSViewRepresentable when you need a specific AppKit view with lightweight lifecycle needs.
• Use NSViewControllerRepresentable when you need controller lifecycle, delegation, or presentation coordination.
• Use direct AppKit window or app hooks when you need NSWindow, responder-chain, menu validation, panels, or app-level behavior.
