Hig Components System

Live Activities

6. Track events with a clear start and end. Deliveries, scores, timers, rides. Design for both Dynamic Island and Lock Screen.

7. Stay updated and timely. Stale data undermines trust. End promptly when the event concludes.

Notifications

8. Respect user attention. Only send notifications for information users genuinely care about. No promotional or low-value notifications.

9. Actionable and self-contained. Include enough context to understand and act without opening the app. Support notification actions. Use threading and grouping.

Complications

10. Focused data on the watch face. Design for the smallest useful representation. Support multiple families. Budget updates wisely.

Home Screen Quick Actions

11. 3-4 most common tasks. Short titles, optional subtitles, relevant SF Symbol icons.

Top Shelf

12. tvOS showcase. Feature content that entices: new episodes, featured items, recent content.

App Clips

13. Instant, focused functionality within a strict size budget. Load quickly without App Store download. Only what's needed for the immediate task, then offer full app install.

App Shortcuts

14. Surface key actions to Siri and Spotlight. Define shortcuts for frequent tasks. Use natural, conversational trigger phrases.
