I am using below code to get the current location.Please help me.This code works in ios 10 but not work in ios 9

 @IBOutlet weak var view_map: GMSMapView!
    let locationManager = CLLocationManager()
    var didFindMyLocation = false
    override func viewDidLoad() {
        super.viewDidLoad()
        view_map.isMyLocationEnabled = true
//        //Location Manager code to fetch current location
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.requestWhenInUseAuthorization()
        if #available(iOS 9.0, *) {
            locationManager.allowsBackgroundLocationUpdates = true
            locationManager.requestLocation()

        }
        locationManager.startUpdatingLocation()
    }
    //Location Manager delegates
       func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let location = locations.last

        let camera = GMSCameraPosition.camera(withLatitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!, zoom: 17.0)

        self.view_map.animate(to: camera)

        //Finally stop updating location otherwise it will come again and again in this delegate
        self.locationManager.stopUpdatingLocation()

    }
    // Handle authorization for the location manager.
    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        switch status {
        case .restricted:
            print("Location access was restricted.")
        case .denied:
            print("User denied access to location.")
            // Display the map using the default location.
            view_map.isHidden = false
        case .notDetermined:
            print("Location status not determined.")
        case .authorizedAlways: fallthrough
        case .authorizedWhenInUse:
            print("Location status is OK.")
        }
    }

    // Handle location manager errors.
    func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
        locationManager.stopUpdatingLocation()
        print("Error: \(error)")
    }

//Add these in your info.plist
<key>NSLocationAlwaysUsageDescription</key>
    <string>Reason to access location background usage description</string>
    <key>NSLocationWhenInUseUsageDescription</key>
    <string>Reason to access location usage description</string>
