Hello Apple Community, What does approach use the Fitness app for swimming distance calculation per set (segment)? I've tried 2 options but all of them have different values than in the Fitness app. Calculation like that: pool length * number of laps = swimming distance BUT the Fitness app sometimes shows other values for distance per set (segment). Fetch all distance values via HKQuantityTypeIdentifier.distanceSwimming (HKSampleQuery`) and than try to match distance values with set (segment) duration. Again I got other values for swimming distance per set, values are bigger than in the Fitness app. let healthStore = HKHealthStore() let distanceType = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.distanceSwimming)! let predicate = HKQuery.predicateForSamples(withStart: startDate as Date, end: endDate as Date?, options: .strictStartDate) let query = HKSampleQuery(sampleType: distanceType, predicate: predicate, limit: HKObjectQueryNoLimit, sortDescriptors: [.init(keyPath: \HKSample.startDate, ascending: true)], resultsHandler: { (query, results, error) in if let error { Logger.e("\(error)") continuation.resume(returning: nil) } continuation.resume(returning: results) }) healthStore.execute(query) Is it possible to get the same swimming distance like in the Fitness app per set via HealthKit?
