How to get HealthKit total steps for previous dates - ios

Question

I am trying to get steps from Health Kit, its working fine for mobile but when i connect Apple Watch my app get more steps then Health kit. i trace it and find that it collect detail record of steps but total steps are less then detail in Health kit.
My App getting the sum of these steps:
But I want To Get these:
Here is My Code:
func MultipleDaysStepsAndActivitiesTest(_ startDate:Date, completion: #escaping (NSDictionary, [HealthKitManuallActivity], NSError?) -> () ) {
let type = HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.stepCount) // The type of data we are requesting
let now = Date()
let newDate = startDate
let predicate = HKQuery.predicateForSamples(withStart: newDate, end: now, options: HKQueryOptions())
var dates = now.datesBetweenGivenDates(startDate,endDate:now)
dates = dates.reversed()
let query = HKSampleQuery(sampleType: type!, predicate: predicate, limit: 0, sortDescriptors: nil) { query, results, error in
var dict:[String:Double] = [:]
if results?.count > 0 {
for result in results as! [HKQuantitySample] {
print(result)
if result.sourceRevision.source.name != kHealthKitSource {
if dict[self.fmt.string(from: result.startDate)] != nil {
dict[self.fmt.string(from: result.startDate)] = dict[self.fmt.string(from: result.startDate)]! + result.quantity.doubleValue(for: HKUnit.count())
} else {
dict[self.fmt.string(from: result.startDate)] = result.quantity.doubleValue(for: HKUnit.count())
}
}
}
}
var sDate = startDate // first date
let cal = Calendar.current
print(dict)
if dict.isEmpty {
while sDate <= Date() {
dict[self.fmt.string(from: sDate)] = 0
sDate = cal.date(byAdding: .day, value: 1, to: sDate)!
}
} else {
while sDate <= Date() {
if dict[self.fmt.string(from: sDate)] == nil {
dict[self.fmt.string(from: sDate)] = 0
}
sDate = cal.date(byAdding: .day, value: 1, to: sDate)!
}
}
// reading activities
self.MultipleDaysWorkouts(startDate, endDate: now, completion: { (activities, error) in
if results?.count == 0 {
for activity in activities {
dict[activity.startDate] = 0.0
}
}
// reading mindfulness activities
self.MultipleDayMindFullnessActivity(startDate, completion: { (mindfulnessActivities, mindError) in
if mindError == nil {
let allActivities = mindfulnessActivities + activities
completion(dict as NSDictionary, allActivities, mindError as NSError?)
}
})
})
}
execute(query)
}

You should use HKStatisticsQuery or HKStatisticsCollectionQuery instead of HKSampleQuery. The statistics queries will de-deuplicate overlapping step samples from different sources to ensure that you do not double-count them. You can find documentation for them here and here.
