What problem does it solve?
HealthKit data is central to many health-focused apps, and securely reading, writing, and querying this data requires careful authorization and pattern usage. This guide provides structured approaches to access the Apple Health store, manage permissions, and perform common data operations at scale.
Core Features & Use Cases
- Authorization: request and manage read/write permissions via HKHealthStore.
- Data access: perform sample, statistics, anchored, and time-series queries to support dashboards and workouts.
- Workout support: create and manage live workout sessions with HKWorkoutSession and HKLiveWorkoutBuilder, including background updates.
- SwiftUI integration: lightweight patterns to integrate HealthKit in SwiftUI apps with observable health managers.
Quick Start
Start by requesting HealthKit authorization for the data you need and then fetch today’s steps and latest heart rate data.
