Is there any way to get Sleep Data by HKSampleQuery like HKStatisticsCollectionQuery?

Hello all!

Unlike Steps and Distance is QuantityType so I can use HKStatisticsCollectionQuery and set options to filter them like below

Code Block language
options: [HKStatisticsOptions.separateBySource, .cumulativeSum]

Sleep is CategoryType so I can only use HKSampleQuery to get data like code below:

Code Block language
func getHealthKitSleep() {
				let healthStore = HKHealthStore()
				let sortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierEndDate, ascending: false)
				// Get all samples from the last 24 hours
				let endDate = Date()
				let startDate = endDate.addingTimeInterval(-1.0 * 60.0 * 60.0 * 24.0)
				let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: [])
				// Sleep query
				let sleepQuery = HKSampleQuery(
						sampleType: HKObjectType.categoryType(forIdentifier: HKCategoryTypeIdentifier.sleepAnalysis)!,
						predicate: predicate,
						limit: 0,
						sortDescriptors: [sortDescriptor]){ (query, results, error) -> Void in
								if error != nil {return}
								// Sum the sleep time
								var minutesSleepAggr = 0.0
								if let result = results {
										for item in result {
												if let sample = item as? HKCategorySample {
														if sample.value == HKCategoryValueSleepAnalysis.asleep.rawValue && sample.startDate >= startDate {
																let sleepTime = sample.endDate.timeIntervalSince(sample.startDate)
																let minutesInAnHour = 60.0
																let minutesBetweenDates = sleepTime / minutesInAnHour
																minutesSleepAggr += minutesBetweenDates
														}
												}
										}
										self.sleep = Double(String(format: "%.1f", minutesSleepAggr / 60))!
										print("HOURS: \(String(describing: self.sleep))")
								}
				}
				// Execute our query
				healthStore.execute(sleepQuery)
		}

This works great if the user has only one sleep app as the source for the data. The problem is if the user is using 2 sleep apps, for example, as sources, the data will be doubled. I just want show sleep data like HealthApp when user change data source priority, is there some ways to do it.
