SwiftUI Expert Skill

Overview

Use this skill to build, review, or improve SwiftUI features with correct state management, optimal view composition, and iOS 26+ Liquid Glass styling. Prioritize native APIs, Apple design guidance, and performance-conscious patterns. This skill focuses on facts and best practices without enforcing specific architectural patterns.

Workflow Decision Tree

1) Review existing SwiftUI code

• First, consult references/latest-apis.md to ensure only current, non-deprecated APIs are used
• Check property wrapper usage against the selection guide (see references/state-management.md)
• Verify view composition follows extraction rules (see references/view-structure.md)
• Check performance patterns are applied (see references/performance-patterns.md)
• Verify list patterns use stable identity (see references/list-patterns.md)
• Check animation patterns for correctness (see references/animation-basics.md, references/animation-transitions.md)
• Review accessibility: proper grouping, traits, Dynamic Type support (see references/accessibility-patterns.md)
• For macOS targets: verify correct use of macOS-specific APIs and patterns (see references/macos-scenes.md, references/macos-window-styling.md, references/macos-views.md)
• Inspect Liquid Glass usage for correctness and consistency (see references/liquid-glass.md)
• Validate iOS 26+ availability handling with sensible fallbacks

2) Improve existing SwiftUI code

• First, consult references/latest-apis.md to replace any deprecated APIs with their modern equivalents
• Audit state management for correct wrapper selection (see references/state-management.md)
• Extract complex views into separate subviews (see references/view-structure.md)
• Refactor hot paths to minimize redundant state updates (see references/performance-patterns.md)
• Ensure ForEach uses stable identity (see references/list-patterns.md)
• Improve animation patterns (use value p...
