Question

我在另一个应用程序中具有相同的代码，并且可以正常运行，现在在该应用程序中，通知组没有通知，并且未调用我的处理程序？由于代码相同，我无法弄清楚这两个应用之间的区别？

 func getHeartRateMaxFromWorkouts(workouts: [HKWorkout], handler: @escaping (careerMaxHeartRatePerWorkoutAsCustomHistoricalSample, careerAverageHeartRatePerWorkoutAsCustomHistoricalSample) -> Void) {

        let workoutsReversed = workouts.reversed()
        guard let heartRateType:HKQuantityType = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.heartRate) else { return }
        let heartRateUnit:HKUnit = HKUnit(from: "count/min")
        var heartRateMaxArrayAsCustomHistoricalSample = [CustomHistoricalSample]()
        var heartRateAvgArrayAsCustomHistoricalSample = [CustomHistoricalSample]()

        //DispatchGroup needed since making async call per workout and need notified when all calls are done
        let dispatchGroup = DispatchGroup()

        for workout in workoutsReversed {

            //predicate
            let startDate = workout.startDate
            let endDate = workout.endDate

            let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: .strictStartDate)

            //descriptor
            let sortDescriptors = [
                NSSortDescriptor(key: HKSampleSortIdentifierEndDate, ascending: true) //Changed this to false so that HRR and MCS would calculate, always check this if not getting these values
            ]
            dispatchGroup.enter()
            let heartRateQuery = HKSampleQuery(sampleType: heartRateType,

                    heartRateAvgArrayAsCustomHistoricalSample.append(averageAsCustomHistoricalSample)

                    dispatchGroup.leave()

                }
            healthStore.execute(heartRateQuery)

        } //End of for workout loop

        dispatchGroup.notify(queue: .main) {

            //Need to sort by date since the dates come back jumbled 
            let sortedReversedHeartRateMaxArrayAsCustomHistoricalSampple = heartRateMaxArrayAsCustomHistoricalSample.sorted { $0.date > $1.date }.reversed() as [CustomHistoricalSample]

             let sortedReversedHeartRateAverageArrayAsCustomHistoricalSampple = heartRateAvgArrayAsCustomHistoricalSample.sorted { $0.date > $1.date }.reversed() as [CustomHistoricalSample]
            print("handler called = \(sortedReversedHeartRateMaxArrayAsCustomHistoricalSampple.count)")

            handler(sortedReversedHeartRateMaxArrayAsCustomHistoricalSampple, sortedReversedHeartRateAverageArrayAsCustomHistoricalSampple)

    } //End getHeartRateMaxFromWorkouts
