After implementation, run fuse-ai-pilot:sniper for validation.
| Feature | Benefit |
|---|---|
| Declarative UI | Less code, automatic updates |
| Cross-platform | Same code for iOS/macOS/watchOS/visionOS |
| @Observable | Simple reactive state |
| SwiftData | Modern persistence with minimal code |
Composable UI building blocks. Extract subviews at 30+ lines.
NavigationStack for stack-based, NavigationSplitView for multi-column.
Modern persistence with @Model. Replaces Core Data for most use cases.
@State for local, @Observable for shared, @Environment for injection.
