Apple HIG guidance for system experience components: widgets, live activities, notifications, complications, home screen quick actions, top shelf, watch faces, app clips, and app shortcuts. Use when asked about: "widget design", "live activity", "notification design", "complication", "home screen quick action", "top shelf", "watch face", "app clip", "app shortcut", "system experience". Also use when the user says "how do I design a widget," "what should my notification look like," "how do Live Activities work," "should I make an App Clip," or asks about surfaces outside the main app. Cross-references: hig-components-status for progress in widgets, hig-inputs for interaction patterns, hig-technologies for Siri and system integration.

Apple HIG: System Experiences
Check for .claude/apple-design-context.md before asking questions. Use existing context and only ask for information not already covered.
Key Principles
-
Glanceable, immediate value. System experiences bring your app's most important content to surfaces the user sees without launching your app. Design for seconds of attention.
-
Respect platform context. A Lock Screen widget has different constraints than a Home Screen widget. A complication is far smaller than a top shelf item.
-
Widgets: show relevant information, not everything. Display the most useful subset, updated appropriately.
-
Support multiple widget sizes with distinct layouts. Each size should be a thoughtful design, not a scaled version of another.
-
Deep-link on tap. Take users to the relevant content, not the app's root screen.
-
Live Activities: track events with a clear start and end. Deliveries, scores, timers, rides. Design for both Dynamic Island and Lock Screen.
-
Stay updated and timely. Stale data undermines trust. End promptly when the event concludes.
-
Respect user attention with notifications. Only send notifications for information users genuinely care about. No promotional or low-value notifications.
-
Notifications: actionable and self-contained. Include enough context to understand and act without opening the app. Support notification actions. Use threading and grouping.
-
Complications: focused data on the watch face. Design for the smallest useful representation. Support multiple families. Budget updates wisely.
-
Home Screen quick actions: 3-4 most common tasks. Short titles, optional subtitles, relevant SF Symbol icons.
-
Top Shelf: tvOS showcase. Feature content that entices: new episodes, featured items, recent content.
-
App Clips: 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: surface key actions to Siri and Spotlight. Define shortcuts for frequent tasks. Use natural, conversational trigger phrases.
Reference Index
| Reference | Topic | Key content | |---|---|---| | widgets.md | Widgets | Glanceable info, sizes, deep linking, timeline | | live-activities.md | Live Activities | Real-time tracking, Dynamic Island, Lock Screen | | notifications.md | Notifications | Attention, actions, grouping, content | | complications.md | Complications | Watch face data, families, budgeted updates | | home-screen-quick-actions.md | Quick actions | Haptic Touch, common tasks, SF Symbols | | top-shelf.md | Top shelf | Featured content, showcase | | app-clips.md | App Clips | Instant use, lightweight, focused task, NFC/QR | | watch-faces.md | Watch faces | Custom complications, face sharing | | app-shortcuts.md | App Shortcuts | Siri, Spotlight, voice triggers |
Output Format
- System experience recommendation -- which surface best fits the use case.
- Content strategy -- what to display, priority, what to omit.
- Update frequency -- refresh rate including system budget constraints.
- Size/family variants -- which to support and how layout adapts.
- Deep link behavior -- where tapping takes the user.
Questions to Ask
- What information needs to surface outside the app?
- Which platform?
- How frequently does the data update?
- What is the primary glanceable need?
