SwiftUI UI/UX Review

Capture a preview screenshot and perform a comprehensive UI/UX review.

Steps

1. Capture the preview

Resolve $ARGUMENTS to a .swift file path. $ARGUMENTS may contain only a View name (e.g. ContentView), so use Glob to find the actual path (e.g. TodoApp/ContentView.swift).

axe preview report <path/to/File.swift> --output <output.png>

axe preview report is preferred over oneshot axe preview because it waits for rendering to complete (--wait, default 10s) and retries on failure.

If the file has multiple #Preview blocks, --output file.png will fail (it requires exactly one preview). In that case:

• Use a directory as --output to capture all, then review each
• Or fall back to axe preview --preview <title|index> (oneshot, no render wait)

Read the captured image with the Read tool.

2. Read the source code

Read the SwiftUI source file (resolved in the previous step) to understand the implementation alongside the visual output.

3. Review the UI

Evaluate the preview image and source code against these criteria:

Layout & Spacing

• Consistent padding and margins
• Proper alignment of elements
• No clipped or overflowing content
• Appropriate use of spacing between elements

Typography

• Readable font sizes (minimum 11pt for body text)
• Proper font weight hierarchy (title > headline > body)
• Text truncation handled gracefully

Color & Contrast

• Sufficient contrast ratios for text readability
• Consistent color usage across elements
• Check source code for semantic colors (.foregroundStyle / .background) vs hardcoded values for Dark Mode support

Apple HIG Compliance

• Standard navigation patterns
• Appropriate use of system components
• Touch target sizes (minimum 44x44pt)
• Safe area handling

Accessibility (source code check)

• Dynamic Type support (look for fixed font sizes vs .font(.body) etc.)
• VoiceOver considerations (.accessibilityLabel, .accessibilityHint)
• Color-only information indicators (should have alternative cues)

4. Report findings

Present findings organized by severity:

1. Issues: Problems that should be fixed (layout bugs, readability issues, HIG violations)
2. Suggestions: Improvements that would enhance quality
3. Good: Aspects that are well-implemented

For each finding, reference the specific line in the source code and suggest a concrete fix.
