How to detect if the user doesn't allow Apple Health Kit Authorisation?

Question

I am using AppleHealthKit in my application. Everything is working correctly. The problem is that I am not able to detect if the user taps "Don't Allow" button when asking for permission.

With this method, my application uses HealthKit, even though the user doesn't allow this.

requestAuthorizationToShareTypes(healthKitTypesToWrite, readTypes: healthKitTypesToRead) { (success, error) -> Void in
        if( completion != nil ) {
            completion(success:success,error:error)
        }

Apple Documentation:

So basically my question is how to detect this?

Answer 1

You cannot detect it, by design:

To help prevent possible leaks of sensitive health information, your app cannot determine whether 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.
