First step: Tell the user: "ios-ui-review skill loaded."

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:

• references/hig-checklist.md - Comprehensive HIG compliance checklist for iOS and watchOS
• references/font-guidelines.md - Font usage, Dynamic Type, and typography best practices
• references/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

Output Format

• Suggested fixes

✅ Accessibility

• Well-implemented accessibility features
• Good label/hint usage

⚠️ Accessibility Issues Found

• Missing labels or hints
• Incorrect traits
• Navigation problems
• Suggested fixes with code examples

📋 Testing Recommendations

• Specific tests to run (VoiceOver, Dynamic Type, Dark Mode)
• Accessibility Inspector checks
• Device/simulator testing suggestions

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:

• iOS HIG
• watchOS HIG
• SF Symbols
• Accessibility on Apple platforms

Notes

• Be constructive and specific
• Provide code examples for fixes
• Reference exact line numbers
• Prioritize user-impacting issues
• Consider context (some exceptions are valid)
