Complete implementation of a SwiftUI iOS app that serves as a "Single Source
of Truth" for health data. The app reads from all Apple Health sources,
detects conflicts between devices, merges data using configurable strategies,
and writes cleaned data back.
Features:
- Phase 1: HealthKit integration with automatic source discovery
- Phase 2: DataReader with conflict detection (time-window based)
- Phase 3: RuleEngine with 8 merge strategies (exclusive, priority, higher wins, etc.)
- Phase 4: MergeEngine for conflict resolution + DataWriter for HealthKit writes
- Phase 5: SwiftUI UI for dashboard, conflicts, rules, and sources management
- Phase 6: Background sync with configurable intervals and push notifications
- Phase 7: Complete rule editor and polished UI components
Supported data types:
- Steps, Heart Rate, Blood Pressure, SpO2, Sleep
- Distance, Floors Climbed, Active Energy, HRV, Respiratory Rate
Architecture: SourceManager -> DataReader -> RuleEngine -> MergeEngine -> DataWriter
