I have issue to request Authorization and get the total sleep hours from HealthKit
func requestAuthorization(completion: @escaping (Bool) -> Void) {
let stepType = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.stepCount)!
let heartRate = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.heartRate)!
let spo2 = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.respiratoryRate)!
let sleepHours = HKObjectType.categoryType(forIdentifier: .sleepAnalysis)
let setType = Set(arrayLiteral: sleep_type_t) //error cannot find 'sleepType' in scope ****
guard let healthStore = self.healthStore else { return completion(false) }
healthStore.requestAuthorization(toShare: [], read: [stepType,heartRate,spo2,sleepHours]) { (success, error) in
completion(success)
}
}
func getSleepHours(completion: @escaping (_ sleepHours: String?) -> Void) {
let sampleType = HKObjectType.categoryType(forIdentifier: HKCategoryTypeIdentifier.sleepAnalysis)!
// Get all samples from the last 24 hours
let endDate = Date()
let startDate = endDate.addingTimeInterval(-1.0 * 60.0 * 60.0 * 24.0)
let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: [])
let sortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierEndDate, ascending: false)
// Sleep query
let sleepQuery = HKSampleQuery(sampleType: sampleType,predicate: predicate,limit: 0,sortDescriptors: [sortDescriptor]) { (query, results, error) -> Void in
if error != nil {return}
// Sum the sleep time
var minutesSleepAggr = 0.0
if let result = results {
for item in result {
if let sample = item as? HKCategorySample {
if sample.value == HKCategoryValueSleepAnalysis.asleep.rawValue && sample.startDate >= startDate {
let sleepTime = sample.endDate.timeIntervalSince(sample.startDate)
let minutesInAnHour = 60.0
let minutesBetweenDates = sleepTime / minutesInAnHour
minutesSleepAggr += minutesBetweenDates
}
}
}
let sleepHours = Double(String(format: "%.1f", minutesSleepAggr / 60))!
let sleepHours2 = "(sleepHours)"
completion(sleepHours2)
print("*** SLEEP HOURS: (String(describing: sleepHours))")
}
}
healthStore?.execute(sleepQuery)
}

I have name the table view cell identifier as cell still keep crashing. Restart XCODE and restart MacBook several times still not working.
