I have solved the problem by creating the two separate func for two separate queries like
func stepCount(completion: @escaping (HKStatisticsCollection?)-> Void){
let stepCount = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.stepCount)!
let startDate = Calendar.current.date(byAdding: .day,value: -7, to: Date())
let anchorDate = Date.monday12AM()
let daily = DateComponents(day : 1)
let predicate = HKQuery.predicateForSamples(withStart: startDate, end: Date(), options: .strictStartDate)
query = HKStatisticsCollectionQuery(quantityType: stepCount, quantitySamplePredicate: predicate,options: .cumulativeSum, anchorDate: anchorDate, intervalComponents: daily)
query!.initialResultsHandler = { query, statisticsCollection, error in
completion(statisticsCollection)
}
if let healthStore = healthStore,let query = self.query{
healthStore.execute(query)
}
}
func swimmingStroke(completion : @escaping (HKStatisticsCollection?)-> Void){
let swimmmingStrokeCount = HKQuantityType.quantityType(forIdentifier: HKQuantityTypeIdentifier.swimmingStrokeCount)!
let startDate = Calendar.current.date(byAdding: .day,value: -7, to: Date())
let anchorDate = Date.monday12AM()
let daily = DateComponents(day : 1)
let predicate = HKQuery.predicateForSamples(withStart: startDate, end: Date(), options: .strictStartDate)
query1 = HKStatisticsCollectionQuery(quantityType: swimmmingStrokeCount, quantitySamplePredicate: predicate,options: .cumulativeSum, anchorDate: anchorDate, intervalComponents: daily)
query1!.initialResultsHandler = { query1, statisticsCollection1, error in
completion(statisticsCollection1)
}
if let healthStore1 = healthStore,let query1 = self.query1{
healthStore1.execute(query1)
}
}
and updating the UI by
if let healthStore1 = healthStore {
healthStore1.authorization { success in
if success{
healthStore1.swimmingStroke{ statisticsCollection1 in
if let statisticsCollection1 = statisticsCollection1{
print(statisticsCollection1)
UpdateUIFromStatistics1(statisticsCollection1)
}else{
print("no statistics Collection Data1")
}
}
}
}
}
if let healthStore = healthStore {
healthStore.authorization { success in
if success{
healthStore.readData{ statisticsCollection in
if let statisticsCollection = statisticsCollection{
print(statisticsCollection)
UpdateUIFromStatistics(statisticsCollection)
}else{
print("no statistics Collection Data")
}
}
}
}
}
