# iOS UI Router

**You MUST use this skill for ANY iOS UI work including SwiftUI, UIKit, layout, navigation, animations, and design.**

## When to Use

Use this router when working with:
- SwiftUI views, state, bindings
- UIKit views and constraints
- Layout issues (Auto Layout, SwiftUI layout)
- Navigation (NavigationStack, deep linking)
- Animations and transitions
- Liquid Glass design (iOS 26+)
- Apple Human Interface Guidelines
- UI architecture and patterns
- Accessibility UI issues

## Conflict Resolution

**ios-ui vs ios-performance**: When UI is slow (e.g., "SwiftUI List slow"):
1. **Try ios-ui FIRST** — Domain-specific fixes (LazyVStack, view identity, @State optimization) often solve UI performance in 5 minutes
2. **Only use ios-performance** if domain fixes don't help — Profiling takes longer and may confirm what domain knowledge already knows

**Rationale**: Jumping to Instruments wastes time when the fix is a known SwiftUI pattern. Profile AFTER trying domain fixes, not before.

## Routing Logic

### SwiftUI Issues

**View not updating** → `/skill axiom-swiftui-debugging`
**Navigation issues** → `/skill axiom-swiftui-nav`
**Performance/lag** → `/skill axiom-swiftui-performance`
**Layout problems** → `/skill axiom-swiftui-layout`
**Stacks/grids/outlines** → `/skill axiom-swiftui-containers-ref`
**Animation issues** → `/skill axiom-swiftui-animation-ref`
**Gesture conflicts** → `/skill axiom-swiftui-gestures`
**Architecture/testability** → `/skill axiom-swiftui-architecture`
**App-level composition** → `/skill axiom-app-composition`
**iOS 26 features** → `/skill axiom-swiftui-26-ref`

### UIKit Issues

**Auto Layout conflicts** → `/skill axiom-auto-layout-debugging`
**Animation timing issues** → `/skill axiom-uikit-animation-debugging`

### Design & Guidelines

**Liquid Glass adoption** → `/skill axiom-liquid-glass`
**Design decisions** → `/skill axiom-hig`
**Typography** → `/skill axiom-typography-ref`
**TextKit/rich text** → `/skill axiom-textkit-ref`
