Thank you, this is exactly what we needed.

I don't think we are on the same page. That run was 10 miles, so it should have been long enough to retrieve information. Better summary of what we are trying to do: We are trying to get a split-by-split breakdown of each mile or kilometer. I attached the Apple UI of what we are looking to re-create. The query above creates the json provided above. Appreicate your help. Thank you

Our results are attached. apple_results.json

Hello, the HKQuantityTypeIdentifierDistanceWalkingRunning is grouped into one and not broken down into laps or segments or markers Below, please find our query and results. Here is our query guard HKHealthStore.isHealthDataAvailable() else { completion(nil, NSError(domain: "HealthKit", code: 1, userInfo: [NSLocalizedDescriptionKey: "HealthKit is not available on this device."])) return } guard let distanceType = HKObjectType.quantityType(forIdentifier: .distanceWalkingRunning) else { completion(nil, NSError(domain: "HealthKit", code: 2, userInfo: [NSLocalizedDescriptionKey: "Unable to create distanceWalkingRunning type."])) return } let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: .strictStartDate) let query = HKSampleQuery(sampleType: distanceType, predicate: predicate, limit: HKObjectQueryNoLimit, sortDescriptors: nil) { _, samples, error in if let error = error { completion(nil, error) return } let runningDistances: NSMutableArray = [] let distanceSamples = samples as? [HKQuantitySample] if let distanceSamples = distanceSamples { for sample in distanceSamples { let distance = sample.quantity.doubleValue(for: HKUnit.meter()) let eventStartDate = self._dateFormatter.string(from: sample.startDate) let eventEndDate = self._dateFormatter.string(from: sample.endDate) let dict:[String:Any] = [ "startDate":eventStartDate, "endDate":eventEndDate, "distance": distance ] runningDistances.add(dict) } } completion(runningDistances, nil) return } let healthStore = HKHealthStore() healthStore.execute(query) }
