I make a MapViewController adopt the CLLocationManagerDelegate protocol this way:

extension MapViewController:CLLocationManagerDelegate{

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

        let usrLocation:CLLocation = locations[0] as CLLocation

        // readable
        print("lat = \(usrLocation.coordinate.latitude)")
        print("lon = \(usrLocation.coordinate.longitude)")

        self.userLocation = usrLocation

        locationManager.stopUpdatingLocation()

    }

    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error)
    {
        print("Error \(error)")
    }

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {

        switch status {
        case .restricted, .denied, .notDetermined:

            // no issue here because I make a very generic request to a server
            // AND I don't need user coordinates

            break

        case .authorizedWhenInUse, .authorizedAlways:

            // here I need user coordinates because I need to request content to a server
            // based on user coordinates but when I check for userLocation
            // at first I find <+0.00000000,+0.00000000> +/- 0.00m (speed -1.00 mps / course -1.00

            print("----------------")
            print(userLocation)
            print("----------------")

            break
        }
    }

I need user location data in the body of the .authorizedWhenInUse/.autorizeAlways case because I need to send current user coordinates to a server. Problem is when I need them I get at first a user location like this one:

 <+0.00000000,+0.00000000> +/- 0.00m (speed -1.00 mps / course -1.00>

userLocation is member of the viewcontroller class and its value is set in locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]). Should I move the request to this function? And how do I check the user status in that context? I only want to make requests for users who authorized the app to retrieve their position. I hope the solution is not a timer and multiple checks, but any help is appreciated :-)
