Я пытаюсь добавитьMKAnnotationView вMKMapView но я не могу сделать это ... Кто-нибудь может мне помочь?

Вот мой код:

override func viewDidLoad() {
    super.viewDidLoad()
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.startUpdatingLocation()
    var latitude:CLLocationDegrees = locationManager.location.coordinate.latitude
    var longitude:CLLocationDegrees = locationManager.location.coordinate.longitude
    var homeLati: CLLocationDegrees = 40.01540192
    var homeLong: CLLocationDegrees = 20.87901079
    var latDelta:CLLocationDegrees = 0.01
    var longDelta:CLLocationDegrees = 0.01
    var theSpan:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, longDelta)
    var myHome:CLLocationCoordinate2D = CLLocationCoordinate2DMake(homeLati, homeLong)
    var myLocation:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
    var theRegion:MKCoordinateRegion = MKCoordinateRegionMake(myLocation, theSpan)
    self.theMapView.setRegion(theRegion, animated: true)
    self.theMapView.mapType = MKMapType.Hybrid
    self.theMapView.showsUserLocation = true
    ///Red Pin
    var myHomePin = MKPointAnnotation()
    myHomePin.coordinate = myHome
    myHomePin.title = "Home"
    myHomePin.subtitle = "Bogdan's home"
    self.theMapView.addAnnotation(myHomePin)

    var anView:MKAnnotationView = MKAnnotationView()
    anView.annotation = myHomePin
    anView.image = UIImage(named:"xaxas")
    anView.canShowCallout = true
    anView.enabled = true
}
