SwiftUI

You MUST use this skill for ANY SwiftUI work including views, state, navigation, layout, animations, architecture, gestures, and debugging.

Non-SwiftUI UI Routes

These topics are part of the broader iOS UI domain but live in separate suites:

UIKit issues

  • Auto Layout conflicts → See axiom-uikit (skills/auto-layout-debugging.md)
  • Animation timing → See axiom-uikit (skills/uikit-animation-debugging.md)
  • SwiftUI ↔ UIKit bridging → See axiom-uikit (skills/uikit-bridging.md)

Design & guidelines

  • Liquid Glass adoption → See axiom-design (skills/liquid-glass.md)
  • SF Symbols → See axiom-design (skills/sf-symbols.md)
  • HIG compliance → See axiom-design (skills/hig.md)
  • Typography → See axiom-design (skills/typography-ref.md)
  • TextKit/rich text → See axiom-uikit (skills/textkit-ref.md)

Other

  • tvOS (focus, remote, text input) → See axiom-swift (skills/tvos.md)
  • App-level composition (root, auth, scenes) → See axiom-design (skills/app-composition.md)
  • Drag/drop, sharing, copy/paste → See axiom-swift (skills/transferable-ref.md)
  • VoiceOver, Dynamic Type → /skill axiom-accessibility
  • UI test flakiness → /skill axiom-testing
  • UX dead ends, dismiss traps → Launch ux-flow-auditor agent

watchOS-specific patterns

  • Glanceable UI, watch navigation, Smart Stack widgets → See axiom-watchos

Conflict Resolution

axiom-swiftui vs axiom-performance: When UI is slow (e.g., "SwiftUI List slow"):

  1. Try axiom-swiftui FIRST — Domain-specific fixes (LazyVStack, view identity, @State optimization) often solve UI performance in 5 minutes
  2. Only use axiom-performance if domain fixes don't help — Profiling takes longer and may confirm what domain knowledge already knows

Decision Tree

digraph swiftui {
    start [label="SwiftUI issue" shape=ellipse];
    what [label="What's wrong?" shape=diamond];

    start -> what;
    what -> "skills/debugging.md" [label="view not updating"];
    what -> "skills/nav.md" [label="navigation"];
    what -> "skills/swiftui-performance.md" [label="slow/lag"];
    what -> "skills/layout.md" [label="adaptive layout"];
    what -> "skills/containers-ref.md" [label="stacks/grids/outlines"];

    what -> "skills/gestures.md" [label="gestures"];
    what -> "skills/search-ref.md" [label="search"];
    what -> "skills/toolbars.md" [label="toolbars / sheet buttons"];
    what -> "skills/26-ref.md" [label="iOS 26 features"];
    what -> "skills/previews.md" [label="slow previews / building good previews"];
    what -> "skills/previews-ref.md" [label="preview API reference"];

}

Automated Scanning

  • Architecture audit → Launch swiftui-architecture-auditor agent
  • Performance scan → Launch swiftui-performance-analyzer agent or /axiom:audit swiftui-performance
  • Navigation audit → Launch swiftui-nav-auditor agent or /axiom:audit swiftui-nav
  • Layout audit → Launch swiftui-layout-auditor agent or /axiom:audit swiftui-layout
  • UX flow audit → Launch ux-flow-auditor agent or /axiom:audit ux-flow
  • Liquid Glass scan → Launch liquid-glass-auditor agent or /axiom:audit liquid-glass (detects migration opportunities AND adoption-completeness gaps: variant discipline for media surfaces, glass-on-glass nesting, missing if #available gates, primary-action tinting, .tabRole(.search); scores ADOPTED / PARTIAL / NOT ADOPTED)
  • TextKit scan → Launch textkit-auditor agent or /axiom:audit textkit (detects fallback triggers, glyph APIs that corrupt complex scripts, missing Writing Tools wiring, AND architectural gaps like missing fallback observation, SwiftUI wrappers dropping TextKit 2 properties, missing isWritingToolsActive guards; scores MODERN / MIXED / LEGACY)

Anti-Rationalization

Thought Reality
"Simple SwiftUI layout, no need" SwiftUI layout has 12 gotchas. skills/layout.md covers all of them.
"I know how NavigationStack works" Navigation has state restoration, deep linking, and identity traps. skills/nav.md prevents 2-hour debugging.
"It's just a view not updating" View update failures have 4 root causes. skills/debugging.md diagnoses in 5 min.
"I'll just add .animation()" Animation issues compound. skills/animation-ref.md has the correct patterns.
"No architecture needed" Even small features benefit from separation. skills/architecture.md prevents refactoring debt.
"I know .searchable" Search has 6 gotchas. skills/search-ref.md covers all of them.
"I'll just add a Done button" Sheets without Cancel break the HIG (updated 2026-03-24). .cancellationAction / .confirmationAction produce HIG-correct placement automatically — skills/toolbars.md Pattern 2 has the rules.
"Previews are slow forever, I'll just use the simulator" Five concrete fixes in skills/previews.md. Rule 4 (auto-refresh off) is 30 seconds and often halves perceived slowness.
"I'll just write a wrapper view for @State in this preview" @Previewable @State (Xcode 16+) eliminates that boilerplate. skills/previews-ref.md has the macro signature.
