Instance Method

authorizationStatus(for:)

Returns the app’s authorization status for sharing the specified data type.

Declaration

func authorizationStatus(for type: HKObjectType) -> HKAuthorizationStatus

Parameters

type

The type of data. This can be any concrete subclass of the HKObjectType class (any of the HKCharacteristicType , HKQuantityType, HKCategoryType, HKWorkoutType or HKCorrelationType classes).

Return Value

A value indicating the app’s authorization status for this type. For a list of possible values, see HKAuthorizationStatus.

Discussion

This method checks the authorization status for saving data.

To help prevent possible leaks of sensitive health information, your app cannot determine whether or not a user has granted permission to read data. If you are not given permission, it simply appears as if there is no data of the requested type in the HealthKit store. If your app is given share permission but not read permission, you see only the data that your app has written to the store. Data from other sources remains hidden.
