如何使用Swift从HealthKit获取ios应用程序的骑行时长

import HealthKit

func requestHealthKitAuthorization() {
    guard HKHealthStore.isHealthDataAvailable() else {
        print("HealthKit is not available on this device.")
        return
    }
    
    let healthStore = HKHealthStore()
    
    let typesToRead: Set<HKObjectType> = [
        HKObjectType.workoutType()
    ]
    
    healthStore.requestAuthorization(toShare: nil, read: typesToRead) { (success, error) in
        if let error = error {
            print("Authorization request failed: \(error.localizedDescription)")
        } else {
            if success {
                print("Authorization request succeeded.")
            } else {
                print("Authorization request denied.")
            }
        }
    }
}

func queryCyclingDuration() {
    guard HKHealthStore.isHealthDataAvailable() else {
        print("HealthKit is not available on this device.")
        return
    }
    
    let healthStore = HKHealthStore()
    
    let cyclingType = HKObjectType.workoutType()
    let predicate = HKQuery.predicateForWorkouts(with: .cycling)
    let sortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierStartDate, ascending: false)
    let query = HKSampleQuery(sampleType: cyclingType, predicate: predicate, limit: 1, sortDescriptors: [sortDescriptor]) { (query, samples, error) in
        if let error = error {
            print("Query failed: \(error.localizedDescription)")
            return
        }
        
        guard let samples = samples as? [HKWorkout], let firstSample = samples.first else {
            print("No cycling workouts found.")
            return
        }
        
        let duration = firstSample.duration
        print("Cycling duration: \(duration) seconds")
    }
    
    healthStore.execute(query)
}
