ios – HealthKit – requestAuthorization(toShare：read：comp

我正在使用 Xcode 8 beta 6,我正在请求访问Health App.请求授权的方法requestAuthorization(toShare：read：completion :)在完成处理程序返回时始终生成true – 在下面的代码中成功.即使我拒绝模拟器中的所有内容,我也会得到真实的结果.
这是我处理授权的代码.我的代码中的某些内容是错误的还是这是一个Xcode错误？

import Foundation
import HealthKit

class HealthManager {
    private let healthStore = HKHealthStore()

    class var sharedInstance: HealthManager {
        struct Singleton {
            static let instance = HealthManager()
        }
        return Singleton.instance
    }

    private var isAuthorized: Bool? = false

    func authorizeHealthKit(completion: ((_ success: Bool) -> Void)!) {
        let writableTypes: Set<HKSampleType> = [HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.distanceWalkingRunning)!,HKWorkoutType.workoutType(),HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.stepCount)!,HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.activeEnergyBurned)!,HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.heartRate)!]
        let readableTypes: Set<HKSampleType> = [HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.distanceWalkingRunning)!,HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.heartRate)!]

        guard HKHealthStore.isHealthDataAvailable() else {
            completion(false)
            return
        }

        // Request Authorization
        healthStore.requestAuthorization(toShare: writableTypes,read: readableTypes) { (success,error) in

            if success {
                completion(true)
                self.isAuthorized = true
            } else {
                completion(false)
                self.isAuthorized = false
                print("error authorizating HealthStore. You're propably on iPad (error?.localizedDescription)")
            }
        }
    }
}

谢谢你的帮助！
