hig-components-status

Original：🇺🇸 English

Translated

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.

Apple HIG: Status Components

Check for

before asking questions. Use existing context and only ask for information not already covered.

Key Principles

Progress Indicators

Show progress for operations longer than a second or two.
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.
Indeterminate when duration is unknown. A spinner communicates work is happening without promising a timeframe. Use for unpredictable network requests.
Prefer progress bars over spinners. Determinate progress feels faster and more trustworthy.
Place indicators where content will appear. Inline progress near the content area, not modal or distant.
Don't stack multiple indicators. Aggregate simultaneous operations into one representation or show the most relevant.

Status Bars

Don't hide the status bar without good reason. Reserve hiding for immersive experiences (full-screen media, games, AR).
Match status bar style to your content. Light or dark for adequate contrast.
Respect safe areas. No interactive content behind the status bar.
Restore promptly when exiting immersive contexts.

Activity Rings

Activity rings are for Move, Exercise, and Stand goals. Don't repurpose the ring metaphor for unrelated data.
Respect ring color conventions. Red (Move), green (Exercise), blue (Stand) are strongly associated with Apple Fitness.
Use HealthKit APIs for activity data rather than manual tracking.
Celebrate completions with animation and haptics when rings close.

Reference Index

Reference	Topic	Key content
progress-indicators.md	Progress bars and spinners	Determinate, indeterminate, inline placement, duration
status-bars.md	iOS/iPadOS status bar	System info, visibility, style, safe areas

Output Format

Indicator type recommendation with rationale (determinate vs indeterminate).
Timing and animation guidance -- duration thresholds, animation style, transitions.
Accessibility -- VoiceOver progress announcements, live region updates.
Platform-specific behavior across targeted platforms.

Questions to Ask

Is the duration known or unknown?
Which platforms?
How long does the operation typically take?
System-level or in-app indicator?
