After some years our app has been writing some data to HealthKit we decided to remove this functionality from the app. Permissions were removed from requestAuthorization(toShare:read:completion:) method. For new users everything works fine, but for users who were already asked for writing permission in Settings toggles for permissions are still on. Is it any way to update toggles list in Settings for actual state of permissions? Thanks in advance.

Hi, I have tried to observe HealthKit data (workouts) with background delivery, but I am faced with a problem - updates don't come when iPhone is locked by Face ID. Everything works fine with an unlocked device. I didn't find any references in the documentations. Is this the expected behavior?
Code:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
HealthManager.shared.startObservingWorkouts {
/*
Don't receive updates
*/
}
return true
}
}
class HealthManager {
static let shared: HealthManager = .init()
private let hkStore = HKHealthStore()
init() { }
func startObservingWorkouts(handleUpdates: @escaping ([HKWorkout]) -> Void) {
hkStore.getRequestStatusForAuthorization(
toShare: [],
read: [.workoutType()])
{ [weak self] status, _ in
guard status == .unnecessary else {
return
}
let prediction = HKQuery.predicateForSamples(
withStart: Date().startOfDay,
end: Date().endOfDay,
options: [.strictStartDate, .strictEndDate]
)
let query = HKObserverQuery(
sampleType: .workoutType(),
predicate: prediction,
updateHandler: { [weak self] _, completionHandler, _ in
self?.getWorkouts {
handleUpdates($0 ?? [])
completionHandler()
}
}
)
self?.hkStore.execute(query)
self?.hkStore.enableBackgroundDelivery(
for: .workoutType(),
frequency: .immediate
) { _, error in
print(error)
}
}
}
private func getWorkouts(handleResult: @escaping ([HKWorkout]?) -> Void) {
let prediction = HKQuery.predicateForSamples(
withStart: Date().startOfDay,
end: Date().endOfDay,
options: [.strictStartDate, .strictEndDate]
)
let query = HKSampleQuery(
sampleType: .workoutType(),
predicate: prediction,
limit: HKObjectQueryNoLimit,
sortDescriptors: nil
) { query, samples, error in
if error != nil {
return
}
guard let samples = samples else {
fatalError("*** Invalid State: This can only fail if there was an error. ***")
}
guard let workouts = samples as? [HKWorkout] else {
return
}
handleResult(workouts)
}
hkStore.execute(query)
}
}
