[Legacy] Apple HealthKit Samples Export Format

Please note that the Apple HealthKit Samples Export Format is a legacy export and we recommend using the Apple HealthKitV2 Samples Export Format. This article should only be used for legacy exports, created prior to 11-April-2022.

The HealthKit samples export encompasses most of the simple data generated by HealthKit (e.g., Heart Rate, Sleep Analysis, Steps, and any other data that is not a workout or activity summary).
