Apple HIG guidance for status and progress UI components including progress indicators, status bars, and activity rings. Use this skill when asked about: "progress indicator", "progress bar", "loading spinner", "status bar", "activity ring", "progress display", determinate vs indeterminate progress, loading states, or fitness tracking rings. Also use when the user says "how do I show loading state," "should I use a spinner or progress bar," "what goes in the status bar," or asks about activity indicators. Cross-references: hig-components-system for widgets and complications, hig-inputs for gesture-driven progress controls, hig-technologies for HealthKit and activity ring data integration.

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 3 are distinctive, and 1 is very specific to this project.

  • ≈0

    Many files like this have a rule of this kind.

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Very specific
  1. Very specific:

    Check for .claude/apple-design-context.md before asking questions.

    line 18
  2. Distinctive:

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

    line 38
  3. Distinctive:

    Restore the status bar promptly: when exiting immersive contexts.

    line 40
  4. Distinctive:

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

    line 42

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

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

  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 progress bars over spinners. Determinate progress feels faster and more trustworthy.
  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.
  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 the status bar promptly when exiting immersive contexts.
  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 HealthKit APIs for activity data rather than manual tracking.
  14. Celebrate completions with animation and haptics when rings close.

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?

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
