The target UUID.
A predicate that matches a specific object based on its UUID.
HealthKit assigns a UUID to each object when it is saved to the HealthKit store. HealthKit uses these IDs to uniquely identify objects from the store. Use this convenience method to create a predicate that matches the object with the provided UUID. The following sample uses both the convenience method and a predicate format string to create equivalent predicates.
