Apple Health data integration is complex due to the need for proper authorization, consistent read/write access, and robust querying and update patterns. This skill consolidates HealthKit usage into a cohesive guide that helps developers implement authorization, sample and statistics queries, background delivery, and workout session management in Swift.
Provide a Swift HealthKit integration plan covering authorization, data queries, background delivery, and workout session setup for a Swift app.

To request HealthKit authorization in Swift, you configure HKHealthStore and request access to specific data types like stepCount and heartRate using HKQuantityTypeIdentifiers. This establishes the necessary permissions for your app to securely read and write health data.
The best way to query HealthKit data for charts is using statistics queries and sample queries. These query patterns allow you to aggregate time-series health data efficiently, enabling your Swift app to render accurate visual representations of the user's health metrics.
Yes, you can use HKWorkoutSession and HKLiveWorkoutBuilder to track live workouts in the background. These components enable your Swift app to manage active workout sessions and record real-time health data updates while running in the background.
Background delivery in HealthKit works by registering observers on HKHealthStore that wake your app up when new health data is available. This allows your Swift app to process incoming health data and execute update logic automatically without requiring user interaction.
You need to use HKUnit and HKQuantityTypeIdentifiers to enforce safe data access patterns in HealthKit. They ensure that health data queries and writes are type-safe and consistently formatted, preventing errors when reading or writing measurements like heart rate and step count.
