# 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`
|
||||
**Drag/drop, copy/paste, sharing** → `/skill axiom-transferable-ref`
|
||||
**Architecture/testability** → `/skill axiom-swiftui-architecture`
|
||||
**App-level composition** → `/skill axiom-app-composition`
|
||||
**Search implementation** → `/skill axiom-swiftui-search-ref`
|
||||
**iOS 26 features** → `/skill axiom-swiftui-26-ref`
|
||||
**UIKit bridging (Representable, HostingController)** → `/skill axiom-uikit-bridging`
|
||||
|
||||
### UIKit Issues
|
||||
|
||||
**Auto Layout conflicts** → `/skill axiom-auto-layout-debugging`
|
||||
**Animation timing issues** → `/skill axiom-uikit-animation-debugging`
|
||||
**SwiftUI embedding (HostingController, HostingConfiguration)** → `/skill axiom-uikit-bridging`
|
||||
|
||||
### Design & Guidelines
|
||||
|
||||
**Liquid Glass adoption** → `/skill axiom-liquid-glass`
|
||||
**SF Symbols (effects, rendering, custom)** → `/skill axiom-sf-symbols`
|
||||
**Design decisions** → `/skill axiom-hig`
|
||||
**Typography** → `/skill axiom-typography-ref`
|
||||
**TextKit/rich text** → `/skill axiom-textkit-ref`
|
||||
|
||||
### tvOS
|
||||
|
||||
**Focus Engine, remote input, TVUIKit, text input** → `/skill axiom-tvos`
|
||||
|
||||
### Accessibility
|
||||
|
||||
**VoiceOver, Dynamic Type** → `/skill axiom-accessibility-diag`
|
||||
|
||||
### Testing
|
||||
|
||||
**UI test flakiness** → `/skill axiom-ui-testing`
|
||||
|
||||
### Automated Scanning
|
||||
|
||||
**Architecture audit** → Launch `swiftui-architecture-auditor` agent (separation of concerns, logic in views, testability)
|
||||
**Performance scan** → Launch `swiftui-performance-analyzer` agent or `/axiom:audit swiftui-performance` (expensive view body ops, unnecessary updates)
|
||||
**Navigation audit** → Launch `swiftui-nav-auditor` agent or `/axiom:audit swiftui-nav` (deep link gaps, state restoration, wrong containers)
|
||||
**Layout audit** → Launch `swiftui-layout-auditor` agent or `/axiom:audit swiftui-layout` (GeometryReader misuse, missing adaptivity, hardcoded breakpoints, identity loss)
|
||||
**UX flow audit** → Launch `ux-flow-auditor` agent or `/axiom:audit ux-flow` (dead ends, dismiss traps, buried CTAs, missing empty/loading/error states)
|
||||
**Liquid Glass scan** → Launch `liquid-glass-auditor` agent or `/axiom:audit liquid-glass` (adoption opportunities, toolbar improvements)
|
||||
**TextKit scan** → Launch `textkit-auditor` agent or `/axiom:audit textkit` (TextKit 1 fallbacks, deprecated glyph APIs, Writing Tools)
|
||||
|
||||
## Decision Tree

||||

|
||||
- Want SwiftUI performance scan (view body ops, unnecessary updates)? → swiftui-performance-analyzer (Agent)
|
||||
- Want navigation audit (deep links, state restoration)? → swiftui-nav-auditor (Agent)
|
||||
- Want layout audit (GeometryReader, adaptivity, hardcoded sizes)? → swiftui-layout-auditor (Agent)
|
||||
- Want UX flow audit (dead ends, dismiss traps, missing states)? → ux-flow-auditor (Agent)
|
||||
- Want Liquid Glass adoption scan? → liquid-glass-auditor (Agent)
|
||||

|

|
||||
## Anti-Rationalization
|
||||
|
||||
| Thought | Reality |
|
||||
|---------|---------|
|
||||
| "Simple SwiftUI layout, no need for the layout skill" | SwiftUI layout has 12 gotchas. swiftui-layout covers all of them. |
|
||||
| "I know how NavigationStack works" | Navigation has state restoration, deep linking, and identity traps. swiftui-nav prevents 2-hour debugging. |
|
||||
| "It's just a view not updating, I'll debug it" | View update failures have 4 root causes. swiftui-debugging diagnoses in 5 min. |
|
||||
| "I'll just add .animation() and fix later" | Animation issues compound. swiftui-animation-ref has the correct patterns. |
|
||||
| "This UI is simple, no architecture needed" | Even small features benefit from separation. swiftui-architecture prevents refactoring debt. |
|
||||
| "UX issues are just polish, we'll fix later" | Dead ends and dismiss traps cause 1-star reviews. ux-flow-audit catches them in minutes. |
|
||||
| "I know how .searchable works" | Search has 6 gotchas (navigation container, isSearching level, suggestion completion). swiftui-search-ref covers all of them. |
|
||||
| "I know SF Symbols, it's just Image(systemName:)" | 4 rendering modes, 12+ effects, 3 Draw playback modes, custom symbol authoring. sf-symbols has decision trees for all of them. |
|
||||
| "Drag and drop is just .draggable and .dropDestination" | UTType declarations, representation ordering, file lifecycle, cross-app transfer gotchas. transferable-ref covers all of them. |
|
||||
| "I'll just wrap this UIView real quick" | UIViewRepresentable has lifecycle, coordinator, sizing, and memory gotchas. uikit-bridging prevents 1-2 hour debugging sessions. |
|
||||
| "tvOS is just iOS on a TV" | tvOS has no persistent storage, no WebView, a dual focus system, and two remote generations. axiom-tvos covers all the traps. |
