To move UI logic into an observable model in SwiftUI, you extract state and behavior from your views into an @Observable model, typically isolating it on @MainActor for easier testing and reuse. This cleanly separates feature logic from view rendering.

Using @Observable models for iOS app architecture isolates feature logic and state into dedicated, testable objects. This separation improves reusability and decouples business logic from SwiftUI and AppKit view rendering complexities.

Handle dependency injection in a Swift observable model by using @Dependency and @ObservationIgnored properties. This approach keeps models decoupled and testable while managing optional presentable children without triggering view updates.

Yes, the observable model pattern works with AppKit and macOS apps. It applies to both SwiftUI and AppKit based applications where isolating feature logic into a dedicated model improves testability and reusability across Apple platforms.

Expose user actions in a Swift @Observable model by creating clearly named async methods that reflect specific user interactions. Bind these methods directly from your SwiftUI view to maintain a clear separation of concerns.
