为什么我的 statisticsUpdateHandler 在 HealthKit 中的苹果锻炼时间不起作用？

Question

检索锻炼时间时，我的 updateHandler 出现问题。事先，我的锻炼时间会更新，在新的一天开始时会重置为零。现在，我的锻炼时间仍然显示前一天的值，并且不会在新的一天重置为零。看来我必须实际获得一些锻炼时间才能实际更新。直到最近我才遇到任何问题，而且从一开始我就没有更改过我的代码。在查看刚刚检索过去 7 天数据的图表时，我注意到了这个问题。步数会更新到新的一天，但不会更新我的运动分钟图。我试过设置断点并查看日期是否有问题，但在检索锻炼时间时没有问题。我还将它与步数数据的逻辑进行了比较，两者都很相似。我有我的 ViewModel 和用于显示锻炼分钟数的视图。我还会附上我的图表图像给你看。

class HealthStoreViewModel: ObservableObject {
    
 var healthStore: HKHealthStore?
 let exerciseTimeType = HKQuantityType.quantityType(forIdentifier: .appleExerciseTime)!
 var exerciseTimeQuery: HKStatisticsCollectionQuery?
 @Published var exerciseTime: [ExerciseTime] = [ExerciseTime]()


//Computed properties
 var currentExTime: Int {
        exerciseTime.last?.exerValue ?? 0
    }
    
    
    //This is for the week starting Sunday - Saturday
    var weeklyExTime: Int {
        exerciseTime.reduce(0) { $0 + $1.exerValue }
    }
    

 let anchorDate = Date.sundayAt12AM()
 let daily = DateComponents(day: 1)

   init(){
        if HKHealthStore.isHealthDataAvailable(){
            healthStore = HKHealthStore()
            showAllExerciseData()
        } else {
            print("HealthKit is unavailable on this platform")
        }

            return
        }

        }
    }

我的视图显示锻炼记录

 HStack(spacing: 50) {
                                ExerciseGaugeView(progress: Double(healthStoreVM.currentExTime), minValue: 0.0, maxValue: Double(healthStoreVM.exerciseDayGoal), title: "Today", dateText: Constants.todayDateString)
                                
      
                                ExerciseGaugeView(progress: Double(healthStoreVM.weeklyExTime),
                                    minValue: 0.0,
                                    maxValue: Double(healthStoreVM.exerciseWeeklyGoal),
                                                  title: "Weekly Total", dateText: Constants.currentWeekDatesString)
                            }

看看4月3日的步数是怎么显示的，锻炼时间还没更新？ 73运动分钟应该归零了
