here is my code

import MapKit
import SwiftUI

struct Maps: View {
    @State private var region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: 37.785834, longitude: -122.406417),latitudinalMeters: 10000, longitudinalMeters: 10000)
    
    @State var tracking : MapUserTrackingMode = .follow
    @State var manager = CLLocationManager()
    @StateObject var managerDelegate = locationDelegate()
    
    var body: some View {
        ZStack{
            VStack{
            Map(coordinateRegion: $region, interactionModes: .all, showsUserLocation: true, userTrackingMode: $tracking)
            }.onAppear{
                manager.delegate = managerDelegate
            }
                
 
        }.navigationBarTitleDisplayMode(.inline)
    }
}

struct Maps_Previews: PreviewProvider {
    static var previews: some View {
        Maps()
    }
}


class locationDelegate: NSObject, ObservableObject, CLLocationManagerDelegate {
    func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) {
        if manager.authorizationStatus == .authorizedWhenInUse {
            manager.startUpdatingLocation()
            
        } else {
            manager.requestWhenInUseAuthorization()
        }
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
       print("Location")
    }
}
