# Apple HIG: Content Components Check for `.claude/apple-design-context.md` before asking questions. Use existing context and only ask for information not already covered. ## Key Principles 1. **Adapt to different sizes and contexts.** Content components must work across screen sizes, orientations, and multitasking configurations. Use Auto Layout and size classes. 2. **Make content accessible.** Charts need audio graph support. Images need alt text. Collections need proper VoiceOver navigation order. All content components need labels and descriptions. 3. **Maintain visual hierarchy.** Use spacing, sizing, and grouping to establish clear information hierarchy. Primary content should be visually prominent. 4. **Use system components first.** Evaluate UICollectionView, SwiftUI Charts, WKWebView before building custom. System components come with built-in accessibility and platform adaptation. 5. **Respect platform conventions.** A collection on tvOS uses large lockups with parallax. The same collection on iOS uses compact cells with touch targets. On visionOS, content gains depth and hover effects. 6. **Handle empty states.** Show a meaningful empty state with guidance on how to populate it, not a blank screen. 7. **Optimize for performance.** Use lazy loading, cell reuse, pagination, and prefetching for large datasets. ## Reference Index | Reference | Topic | Key content | |---|---|---| | [charts.md](references/charts.md) | Charts | Swift Charts, bar/line/area/point
