HealthKit Fetch Workout Time, Distance, Avg Heart Rate - swift

Question

I was able to fetch some of the details separated from HealthKit app, but i have a missing points that i need help with such as getting the below exact data for each workout.
And here is what i tried for Exercise time:
func getExerciseTime(forDate date: Date, _ completion: ((Double, Error?) -> Void)!) {
let cal = Calendar.current
let startDate = cal.startOfDay(for: date)
var comps = DateComponents()
comps.day = 1
comps.second = -1
let endDate = cal.date(byAdding: comps, to: startDate)
let stepsCount = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.appleExerciseTime)
let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: .strictStartDate)
let interval: NSDateComponents = NSDateComponents()
interval.day = 1
let query = HKStatisticsCollectionQuery(quantityType: stepsCount!, quantitySamplePredicate: predicate, options: [.cumulativeSum], anchorDate: startDate as Date, intervalComponents: interval as DateComponents)
query.initialResultsHandler = { query, results, error in
if error != nil {
// Something went Wrong
return
}
var exercise = 0.0
if let myResults = results, let endDate = endDate {
myResults.enumerateStatistics(from: startDate, to: endDate) { statistics, _ in
if let quantity = statistics.sumQuantity() {
exercise = quantity.doubleValue(for: HKUnit.minute())
}
}
}
completion(round(exercise), error)
}
healthKitStore.execute(query)
}
I was able to get the beats but not the average heart rate for the workout:
func getAverageHeartRate(date:Date,completion:
#escaping ([HKWorkout]?, Error?) -> Void) {
guard let heartRateType =
HKObjectType.quantityType(forIdentifier:
HKQuantityTypeIdentifier.heartRate) else {
fatalError("*** Unable to create a Heart rate type ***")
}
let cal = Calendar.current
let startDate = cal.startOfDay(for: date)
var comps = DateComponents()
comps.day = 1
comps.second = -1
let endDate = cal.date(byAdding: comps, to: startDate)
// Get all workouts that only came from this app.
let workoutPredicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: .strictStartDate)
let startDateSort = NSSortDescriptor(key: HKSampleSortIdentifierStartDate, ascending: true)
let query = HKSampleQuery(sampleType: heartRateType,
predicate: workoutPredicate,
limit: 0,
sortDescriptors: [startDateSort]) { (sampleQuery, results, error) -> Void in
guard let heartRateSamples = results as? [HKQuantitySample] else {
// Perform proper error handling here.
return
}
// Use the workout's Heart rate samples here.
for heartrate in heartRateSamples {
let beats: Double? = heartrate.quantity.doubleValue(for: HKUnit.count().unitDivided(by: HKUnit.minute()))
print(heartrate.startDate, heartrate.endDate)
print(beats)
guard beats != nil else {
return
}
}
}
healthKitStore.execute(query)
And lastly:
func getWorkOutData(forDate date: Date, _ completion: ((Int, Error?) -> Void)!) {
let cal = Calendar.current
let startDate = cal.startOfDay(for: date)
var comps = DateComponents()
comps.day = 1
comps.second = -1
let endDate = cal.date(byAdding: comps, to: startDate)
let sortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierStartDate, ascending: true)
let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: HKQueryOptions())
let sampleQuery = HKSampleQuery(sampleType: HKWorkoutType.workoutType(), predicate: predicate, limit: 0, sortDescriptors: [sortDescriptor]) { (_, results, error ) -> Void in
var eligible = 0
if let myResults = results as? [HKWorkout] {
for workout in myResults where workout.duration >= 600 {
eligible += 1
}
}
completion(eligible, error)
}
healthKitStore.execute(sampleQuery)
}
1- I was able to get the heartbeats not the avg heart rate per workout.
2- I couldn't connect the data from each one to be like a workout model that contains Time,Distance,AvgHeart rate.
