Hi, I'm currently working on a spot tracking app, which means it's on a user-defined geographical area. I have a problem, I don't know how to get the coordinates of the place where the user presses on the map and convert them in order to get the geographic coordinates for further processing. Here's my code: if you have any ideas, don't hesitate ^^thanks in advance :)

import SwiftUI
import CoreLocation
import MapKit

struct AddZoneView: View {

    let locationManager = Location()
    let viewController = AddZoneController()
    @State var pinLocation: CLLocationCoordinate2D?
    @State private var userLocation: CLLocationCoordinate2D?

    var body: some View {
        NavigationView {
            Map(coordinateRegion: .constant(MKCoordinateRegion(
                center: userLocation ?? CLLocationCoordinate2D(
                    latitude: locationManager.userLocation?.latitude ?? 0,
                    longitude: locationManager.userLocation?.longitude ?? 0
                ),
                span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01)
            )), showsUserLocation: true)
            .frame(maxWidth: .infinity, maxHeight: .infinity)
            .onTapGesture { gesture in
                let tap = gesture.location
                pinLocation = coordinate(for: tap)
                viewController.addMarker(longitude: pinLocation?.longitude ?? 0, latitude: pinLocation?.latitude ?? 0)

            }
            .ignoresSafeArea(.all)
        }
        func coordinate(for location: CGPoint) -> CLLocationCoordinate2D {
            let mapRect = MKMapRect(
                origin: MKMapPoint(x: location.x, y: location.y),
                size: MKMapSize(width: 0, height: 0)
            )
            let coordinate = mapRect.origin.coordinate
            return coordinate
        }
    }
}

#Preview {
    AddZoneView()
