Does the Apple Healthkit store a unique identifier (UUID) developers can retrieve?

Is there a unique identifier like a UUID attached to a Apple HealthKit, ResearchKit, or CareKit instance that would allow developers to know if the same user has multiple iPhones? Is there something that links a users healthKit to their iCloud account?

Solution

  • No, it does not enable you to identify the user across devices.
