# iOS Design System (SwiftUI)
## **Priority: P2 (OPTIONAL)**
Enforce design token usage in SwiftUI. Follow Apple HIG for iOS-native feel.
## Token Structure
Define tokens in `Theme/` folder: Colors via Asset Catalog (`Color("Name")`), `Spacing` enum for all margins, `Font` extensions for typography. See [Token Structure & Examples](references/example.md).
## Anti-Patterns
- **No Hex Colors**: Define in asset catalog, use `Color("Name")`.
- **No Magic Spacing**: Use `Spacing.md` not `spacing: 16`.
- **No System Colors for Brand**: Use `.appPrimary` not `Color.blue`.
