# SwiftUI Expert Skill

## Operating Rules

- Consult `references/latest-apis.md` at the start of every task to avoid deprecated APIs
- Prefer native SwiftUI APIs over UIKit/AppKit bridging unless bridging is necessary
- Focus on correctness and performance; do not enforce specific architectures (MVVM, VIPER, etc.)
- Encourage separating business logic from views for testability without mandating how
- Follow Apple's Human Interface Guidelines and API design patterns
- Only adopt Liquid Glass when explicitly requested by the user (see `references/liquid-glass.md`)
- Present performance optimizations as suggestions, not requirements
- Use `#available` gating with sensible fallbacks for version-specific APIs

## Task Workflow

### Review existing SwiftUI code
- Read the code under review and identify which topics apply
- Flag deprecated APIs (compare against `references/latest-apis.md`)
- Run the Topic Router below for each relevant topic
- Validate `#available` gating and fallback paths for iOS 26+ features

### Improve existing SwiftUI code
- Audit current implementation against the Topic Router topics
- Replace deprecated APIs with modern equivalents from `references/latest-apis.md`
- Refactor hot paths to reduce unnecessary state updates
- Extract complex view bodies into separate subviews
- Suggest image downsampling when `UIImage(data:)` is encountered (optional optimization, see `references/image-optimization.md`)

### Implement new SwiftUI feature
- Design data flow first: identify owned vs injected state
- Structure views for optimal diffing (extract subviews early)
- Apply correct animation patterns (implicit vs explicit, transitions)
- Use `Button` for all tappable elements; add accessibility grouping and labels
- Gate version-specific APIs with `#available` and provide fallbacks

### Topic Router

Consult the reference file for each topic relevant to the current task:

| Topic | Reference |
|-------|-----------|
| State management | `references/state-management.md` |
| View composition | `references/view-structure.md` |
| Performance | `references/performance-patterns.md` |
| Lists and ForEach | `references/list-patterns.md` |
| Layout | `references/layout-best-practices.md` |
| Sheets and navigation | `references/sheet-navigation-patterns.md` |
| ScrollView | `references/scroll-patterns.md` |
| Animations (basics) | `references/animation-basics.md` |
| Animations (transitions) | `references/animation-transitions.md` |
| Animations (advanced) | `references/animation-advanced.md` |
| Accessibility | `references/accessibility-patterns.md` |
| Swift Charts | `references/charts.md` |
| Charts accessibility | `references/charts-accessibility.md` |
| Image optimization | `references/image-optimization.md` |
| Liquid Glass (iOS 26+) | `references/liquid-glass.md` |
| macOS scenes | `references/macos-scenes.md` |
| macOS window styling | `references/macos-window-styling.md` |
| macOS views | `references/macos-views.md` |
| Deprecated API lookup | `references/latest-apis.md` |

## Correctness Checklist

These are hard rules -- violations are always bugs:

- [ ] `@State` properties are `private`
- [ ] `@Binding` only where a child modifies parent state
- [ ] Passed values never declared as `@State` or `@StateObject` (they ignore updates)
- [ ] `@StateObject` for view-owned objects; `@ObservedObject` for injected
- [ ] iOS 17+: `@State` with `@Observable`; `@Bindable` for injected observables needing bindings
- [ ] `ForEach` uses stable identity (never `.indices` for dynamic content)
- [ ] Constant number of views per `ForEach` element
- [ ] `.animation(_:value:)` always includes the `value` parameter
- [ ] iOS 26+ APIs gated with `#available` and fallback provided
- [ ] `import Charts` present in files using chart types
