majiayu000 UI Review Skill
Performs comprehensive UI/UX review of SwiftUI code against Apple's Human Interface Guidelines, font best practices, and accessibility standards for iOS and watchOS.
When This Skill Activates
Use this skill when the user:
- Asks to review UI/UX code
- Mentions HIG compliance or Apple guidelines
- Requests accessibility audit
- Wants font usage checked
- Asks about Dynamic Type support
- Requests design review against Apple standards
Review Process
1. Identify Files to Review
- If user specifies files/views, review those
- Otherwise, ask which views to review or scan recent SwiftUI files
- Prioritize user-facing views over components
2. Load Reference Materials
Before starting the review, familiarize yourself with the reference materials by reading the following files in .claude/skills/ui-review/:
- hig-checklist.md - Comprehensive HIG compliance checklist for iOS and watchOS
- font-guidelines.md - Font usage, Dynamic Type, and typography best practices
- accessibility-quick-ref.md - Quick reference for accessibility implementation
You may also reference the official Apple guidelines using WebFetch when needed:
- iOS HIG: https://developer.apple.com/design/human-interface-guidelines/designing-for-ios
- watchOS HIG: https://developer.apple.com/design/human-interface-guidelines/designing-for-watchos
3. Review Categories
Apply these review categories based on the code type:
HIG Compliance:
- Layout & spacing (tap targets, safe areas, padding)
- Navigation patterns (NavigationStack, sheets, alerts)
- Colors & visuals (semantic colors, dark mode, contrast)
- Platform-specific requirements (iOS vs watchOS)
- Loading/empty/error states
Font Usage:
- Dynamic Type support
- System text styles vs fixed sizes
- Font hierarchy and semantic usage
- Custom fonts scaling properly
- Text formatting and truncation
Accessibility:
- Labels and hints for interactive elements
- Traits and roles
- VoiceOver navigation order
- Custom actions
- Dynamic content announcements
- Testing with assistive technologies
4. Common Issues to Flag
Anti-patterns:
- Hardcoded colors (
.foregroundColor(.black)) - Fixed font sizes (
.font(.system(size: 14))) - Missing accessibility labels on icon-only buttons
- Tap targets smaller than 44pt (iOS) or 40pt (watchOS)
- Important info conveyed by color only
- Missing loading/error states
- Direct UIColor usage (use
Color(.systemBackground)) .frame()without considering Dynamic Type expansion- Missing keyboard shortcuts (iPad/Mac)
Good Patterns:
- Semantic color usage
- System font styles with Dynamic Type
- Comprehensive accessibility labels
- Clear visual hierarchy
- Consistent spacing
- Proper error handling
- Responsive layouts

Example Review Output
Reviewing: AddOrUpdateExpenseView.swift
✅ HIG Compliance
- Good use of semantic colors throughout
- Proper NavigationStack implementation
- Safe area handling is correct
⚠️ HIG Issues Found
1. AddOrUpdateExpenseView.swift:145 - Delete button tap target may be small
Suggested fix: Ensure .frame(minWidth: 44, minHeight: 44)
2. AddOrUpdateExpenseView.swift:203 - Hardcoded color
Current: .foregroundColor(.red)
Suggested: .foregroundColor(Color(.systemRed))
✅ Font Usage
- Excellent use of .headline for section headers
- Proper .body for content text
⚠️ Font Issues Found
1. AddOrUpdateExpenseView.swift:178 - Hardcoded font size
Current: .font(.system(size: 14))
Suggested: .font(.subheadline)
✅ Accessibility
- Good labels on most form fields
- Proper form structure
⚠️ Accessibility Issues Found
1. AddOrUpdateExpenseView.swift:92 - Icon button missing label
Current: Button { } label: { Image(systemName: "calendar") }
Suggested: Add .accessibilityLabel("Select date")
📋 Testing Recommendations
1. Test with VoiceOver enabled
2. Test at largest Dynamic Type size (Accessibility → Display)
3. Verify in Dark Mode
4. Use Accessibility Inspector to check contrast ratios
References
Always reference these when in doubt:
Notes
- Be constructive and specific
- Provide code examples for fixes
- Reference exact line numbers
- Prioritize user-impacting issues
- Consider context (some exceptions are valid)
