Migrating from ObservableObject to @Observable in SwiftUI involves using the Swift Observation framework for state management. This modern approach replaces the older Combine-based pattern, streamlining state updates in your views.

The best way to replace Core Data with SwiftData is using @Model for persistence and @Query to fetch data. This modern approach avoids Core Data entirely for new code, simplifying database management in iOS 18+.

Modern Swift 6 concurrency replaces DispatchQueue with async/await, actor, and @MainActor. You apply these structured concurrency patterns to handle asynchronous tasks safely across API clients and authentication flows.

Claude often generates outdated Swift code using NavigationView. To enforce modern SwiftUI APIs, you must replace NavigationView with NavigationStack and adopt ContentUnavailableView for empty states.

Yes, you can use this skill to review existing iOS code for outdated Swift patterns. It evaluates code generation, architecture decisions, and reviews involving SwiftUI, SwiftData, async/await, and NavigationStack.
