Quick Reference
SwiftUI: Use @Observable macro (not ObservableObject) for view models. @MainActor for UI code. async/await for async operations. actors for shared mutable state. @State for ownership, plain property for dependency. .task modifier auto-cancels.
Use When
- Building iOS/macOS apps with SwiftUI
- Implementing state management in Swift
- Using Swift Concurrency patterns
- Structuring SwiftUI projects
Skip When
- UIKit-only applications
- Cross-platform frameworks (Flutter, React Native)
- Pre-iOS 17 targets without @Observable
