iOS Design Review

Validate SwiftUI/UIKit code against Apple Human Interface Guidelines.

When to Use

• After generating SwiftUI components
• Before submitting iOS code for review
• Auditing existing iOS UI code
• Checking accessibility compliance

Review Checklist

1. Colors & Theming

• Uses semantic colors (Color.primary, Color(.systemBackground))
• No hardcoded hex colors
• Works in both Light and Dark mode
• High contrast mode support

2. Typography

• Uses system fonts (San Francisco)
• Supports Dynamic Type
• Proper text styles (.headline, .body, .caption)
• No fixed font sizes for body text

3. Touch Targets

• Minimum 44×44 points for interactive elements
• Adequate spacing between tappable items (12-24pt)
• No gesture conflicts with system gestures

4. Accessibility

• VoiceOver labels on icon-only buttons
• accessibilityElement(children: .combine) for grouped content
• accessibilityHidden(true) for decorative elements
• Meaningful accessibility hints where needed

5. Navigation

• Tab bar for 2-5 primary destinations (not actions)
• Navigation titles present
• Back button behavior correct
• Modal dismiss patterns (swipe, X button)

6. SF Symbols

• Uses SF Symbols over custom icons where possible
• Correct rendering mode (monochrome/hierarchical/palette)
• Symbols scale with Dynamic Type

7. Layout

• Safe area respected
• Adapts to different screen sizes
• Proper keyboard avoidance
• No content clipping

#### Warnings
- Line 23: Hardcoded color `Color(hex: "#FF5733")`
  Fix: Use `Color.accentColor` or semantic color

#### Suggestions
- Line 67: Consider adding accessibilityLabel to icon button

### Summary
