How do I get data like move and exercise time from HealthKit

Code Block 
import SwiftUI
import HealthKit
struct Health: View {
    var body: some View {
        let healthStore = HKHealthStore()
        let objectTypes: Set<HKObjectType> = [
            HKObjectType.activitySummaryType()
        ]
        healthStore.requestAuthorization(toShare: nil, read: objectTypes) { (success, error) in
        
            // Authorization request finished, hopefully the user allowed access!
            let calendar = Calendar.autoupdatingCurrent
            var dateComponents = calendar.dateComponents(
                [ .year, .month, .day ],
                from: Date()
            )
            // This line is required to make the whole thing work
            dateComponents.calendar = calendar
            let predicate = HKQuery.predicateForActivitySummary(with: dateComponents)
            et; query = HKActivitySummaryQuery(predicate: predicate) { (query, summaries, error) in
                guard let summaries = summaries, summaries.count > 0
                else {
                    return
                }
                let sandUnit = HKUnit.count()
                let standHours = summary.appleStandHours.doubleValue(for: standUnit)
            }
            
        }
    }
}
struct Health_Previews: PreviewProvider {
    static var previews: some View {
        Health()
    }
}
