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 the layout system appropriate to the framework (SwiftUI layout or Auto Layout), and use size classes where available.

2. Make content accessible. Provide chart summaries and appropriate accessible data navigation; Swift Charts includes a default Audio Graphs implementation. Give meaningful images descriptive accessibility labels and hide decorative or redundant images. Collections need a logical VoiceOver navigation order.

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 provide accessibility and adaptation defaults; still test labels, interactions and supported platform versions.

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	Charts	Swift Charts, bar/line/area/point marks, chart accessibility, audio graphs
collections.md	Collections	Grid/list layouts, compositional layout, selection, reordering, diffable data sources
image-views.md	Image Views	Aspect ratio handling, content modes, SF Symbol images, accessibility
image-wells.md	Image Wells	Drag-and-drop image selection, macOS-specific, placeholder content
color-wells.md	Color Wells	Color selection UI, system color picker, custom color spaces
web-views.md	Web Views	WKWebView, SFSafariViewController, navigation controls, content restrictions
activity-views.md	Activity Views	Share sheets, activity items, custom activities, action extensions
lockups.md	Lockups	Image+text elements, tvOS card layouts, focus effects, shelf layouts

Component Selection Guide

Content Need	Recommended Component	Platform Notes
Visualizing quantitative data	Charts (Swift Charts)	iOS 16+, macOS 13+, watchOS 9+
Browsing a grid or list of items	Collection View	Compositional layout for complex arrangements
Displaying a single image	Image View	Support aspect ratio fitting; provide accessibility description
Selecting an image via drag or browse	Image Well	macOS primarily; use image pickers on iOS
Selecting a color	Color Well	Triggers system color picker; macOS, iOS 14+
Showing web content inline	Web View (WKWebView)	On supported UIKit platforms consider SFSafariViewController; on macOS use the default browser for external links
Sharing content to other apps	Activity View	System share sheet with configurable activity types
Content card (image + text)	Lockup	TVUIKit lockups are tvOS-specific; adapt the content-card pattern with native components elsewhere

Output Format

1. Component recommendation with rationale, referencing the relevant HIG reference file.
2. Configuration guidance -- key properties and setup.
3. Accessibility requirements for the recommended component.
4. Platform-specific notes for targeted platforms.

Questions to Ask

1. What type of content? (Quantitative data, images, web content, browsable collection, share action?)
2. Which platforms?
3. Static or dynamic content?
4. How much content? (Few items vs hundreds/thousands affects component choice and optimization.)

Use @hig-components-content for this task: Apple Human Interface Guidelines for content display components.

Limitations

• Bundled HIG pages are reference snapshots, not a live compatibility matrix. Verify API availability against the target SDK and deployment version. macOS uses native sharing APIs rather than UIActivityViewController; do not infer API portability from a shared visual pattern.
• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
