watchOS Platform
watchOS-specific development for Apple Watch experiences.
Agent Workflow (MANDATORY)
Before ANY implementation, use TeamCreate to spawn 3 agents:
- fuse-ai-pilot:explore-codebase - Analyze existing watchOS patterns
- fuse-ai-pilot:research-expert - Verify latest watchOS 26 docs via Context7/Exa
- mcp__apple-docs__search_apple_docs - Check watchOS patterns
After implementation, run fuse-ai-pilot:sniper for validation.
Overview
When to Use
- Building Apple Watch apps
- Creating watch face complications
- Workout and fitness tracking
- Health data access (HealthKit)
- iPhone-Watch communication
Why watchOS Skill
| Feature | Benefit | |---------|---------| | Complications | Glanceable data on watch face | | Workouts | Fitness and health tracking | | HealthKit | Access health metrics | | Connectivity | Sync with iPhone |
Reference Guide
| Need | Reference | |------|-----------| | Watch face complications | [complications.md](references/complications.md) | | Workout sessions, HealthKit | [workouts.md](references/workouts.md) | | iPhone ↔ Watch sync | [watch-connectivity.md](references/watch-connectivity.md) |
Design Considerations
Screen Size
- Small display, large touch targets
- Glanceable information
- Minimal text, clear icons
Interactions
- Digital Crown for scrolling/input
- Force Touch (older watches)
- Gestures: swipe, tap
Battery
- Minimize background work
- Use complications for updates
- Efficient data transfer
Best Practices
- Glanceable - Quick information access
- Large targets - Easy tapping
- Minimal input - Reduce typing
- Complications - Update watch face data
- Background refresh - Efficient updates
- Test on device - Simulator differs from hardware
