Apple HIG: Status Components

Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.

Key Principles

Progress Indicators

1. Show progress for operations longer than a second or two.

2. Determinate when duration/percentage is known. A filling progress bar gives users a clear sense of remaining work. Use for downloads, uploads, or any measurable process.

3. Indeterminate when duration is unknown. A spinner communicates work is happening without promising a timeframe. Use for unpredictable network requests.

4. Prefer determinate progress only when measurable. Never invent a percentage; use a spinner for unknown work or constrained background status, consistent with the platform reference.

5. Place indicators where content will appear. Inline progress near the content area, not modal or distant.

6. Don't stack multiple indicators. Aggregate simultaneous operations into one representation or show the most relevant.

Status Bars

7. Don't hide the status bar without good reason. Reserve hiding for immersive experiences (full-screen media, games, AR).

8. Match status bar style to your content. Light or dark for adequate contrast.

9. Respect safe areas. No interactive content behind the status bar.

10. Restore promptly when exiting immersive contexts.

Activity Rings

11. Activity rings are for Move, Exercise, and Stand goals. Don't repurpose the ring metaphor for unrelated data.

12. Respect ring color conventions. Red (Move), green (Exercise), blue (Stand) are strongly associated with Apple Fitness.

13. Use authorized HealthKit APIs for activity data; respect permission denial and keep health data private. Do not infer absent activity from missing access.

14. Respect motion/haptic preferences for optional completion feedback. Never fabricate activity completion or duplicate system notifications.

Output Format

1. Indicator type recommendation with rationale (determinate vs indeterminate).

2. Timing and animation guidance -- duration thresholds, animation style, transitions.

3. Accessibility -- VoiceOver progress announcements, live region updates.

4. Platform-specific behavior across targeted platforms.

Questions to Ask

1. Is the duration known or unknown?

2. Which platforms?

3. How long does the operation typically take?

4. System-level or in-app indicator?
