what is heallthkit

HealthKit is a framework provided by Apple that offers a centralized and encrypted repository for users' health data. With the user's permission, apps can access this data to create experiences that help people maintain and improve their health. HealthKit allows apps to query and write health data, compute statistics over time, and register for updates when data changes. It supports a wide range of health domains, including activity, heart, sleep, and clinical health records like immunizations and procedures.

Recently, HealthKit has been extended to visionOS, enabling developers to create immersive and collaborative health experiences on the Apple Vision Pro. This includes the ability to read and write data, compute statistics, and handle updates in a spatial computing environment. Developers need to consider guest user support, as guest users are restricted from authorizing health data access.
