我面临的问题是，我试图从跑步锻炼中获得潜在的GPS点，但没有找到锻炼。
下面的第一个函数fetchRunningWorkouts完成得很好，它是在fetchRunningWorkoutRoute失败而没有找到数据时完成的。我可以看到设备上有可用的运行，我可以看到我有所需查询的适当授权。
注意：为了清楚起见，我调用KHealthStore().execute()

func fetchRunningWorkouts() {
        // Create a predicate to filter for running workouts
        let workoutPredicate = HKQuery.predicateForWorkouts(with: .running)

        // Create a query to fetch running workouts
        let workoutQuery = HKSampleQuery(
            sampleType: HKWorkoutType.workoutType(),
            predicate: workoutPredicate,
            limit: 8,
            sortDescriptors: nil
        ) { (query, samples, error) in
             
             fetchRunningWorkoutRoute(workout: workout)
             ....
     }

func fetchRunningWorkoutRoute(workout: HKWorkout) {

    let workoutRouteQuery = HKSampleQuery(
        sampleType: HKSeriesType.workoutRoute(),
        predicate: HKQuery.predicateForObjects(from: workout),
        limit: HKObjectQueryNoLimit,
        sortDescriptors: nil
    ) { (query, samplesOrNil, errorOrNil) in
          guard errorOrNil == nil else {
              print("HealthKit query error: \(errorOrNil!.localizedDescription)")
              return
          }

        guard let samples = samplesOrNil as? [HKWorkoutRoute], let route = samples.first else {
            print("No workout route found in HealthKit.")
            return
        }
           ....
        }
