Use NSViewRepresentable to wrap AppKit views for use inside SwiftUI hierarchies, and NSHostingView or NSHostingController to embed SwiftUI content inside AppKit apps. The skill's appkit-swiftui-bridge module covers state management between the two frameworks.

Use SwiftData for new projects, defining @Model classes with explicit relationships and delete rules, and query with @Query in SwiftUI views. Core Data remains appropriate for legacy migrations or advanced features not yet available in SwiftData.

Yes, Liquid Glass is applied through system materials like .ultraThinMaterial and .regularMaterial, semantic colors, subtle shadows, and spring animations. The skill also references a dedicated liquid-glass skill for the newer .glassEffect() API.

Add accessibilityLabel and accessibilityHint to interactive elements, combine child elements where appropriate, support keyboard navigation with @FocusState, and respect Dynamic Type and reduce-motion preferences. Test with VoiceOver enabled using Cmd+F5.

Choose AppKit for complex table views with custom cells, advanced text editing via NSTextView, precise custom drawing, performance-critical UI, or features not yet available in SwiftUI. Hybrid approaches using hosting controllers are common.

Create SwiftData @Model classes mirroring your Core Data entities, then run a migration utility that fetches NSManagedObject instances and inserts converted models into a ModelContext. The skill's data-persistence module includes a step-by-step migration example.
