Build iOS apps using Swift 6 and iOS 18+ best practices. This skill ensures code uses modern patterns: SwiftData (not Core Data), Observation framework (not Combine), Swift concurrency (not GCD), and current SwiftUI APIs.

Swift 6 Concurrency First Always use Swift concurrency (async/await, actor, @MainActor) instead of GCD or completion handlers. Use structured concurrency (TaskGroup, async let) over unstructured tasks.

Observation Framework Over Combine Use @Observable macro for state management instead of ObservableObject with @Published. The Observation framework is more efficient and has cleaner syntax.

使用 Swift 6、iOS 18+、SwiftUI、SwiftData 和現代並發模式建立 iOS 應用程式的指南。在編寫 Swift/iOS 程式碼、設計應用程式架構或現代化遺留模式時使用。防止過時的模式，如 Core Data、ObservableObject、DispatchQueue 和 NavigationView。 來源：fal3/claude-skills-collection。
