(MapView) Userlocation image changed help to restore

I am working with MapKit and I changed the Annotation´s image, but the problem is, the Userlocation (blue dot) also changed its picture (I didn't want that). How can I restore it back to normal. Also, I added a small button to the callout which (as you may have guessed) was added to my location and it was not supposed to be there. My code is the following...

    func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
        if !(annotation is MKUserLocation) {
            print("annotation is MKUserLocation")
        }
        var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: "identifier")
            if annotationView == nil{
                annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: "identifier")
                annotationView!.canShowCallout = true
                annotationView!.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)

                let pinImg = UIImage(named: "curz")
                let size = CGSize(width: 50, height: 50)
                UIGraphicsBeginImageContext(size)
                pinImg!.draw(in: CGRect(x: 0, y: 0, width: size.width, height: size.height))
                let resizedImage = UIGraphicsGetImageFromCurrentImageContext()
                UIGraphicsEndImageContext()
                annotationView!.image = resizedImage
                }
        else {
        annotationView!.annotation = annotation
      }
    return annotationView
   }

        //Var SelectedAnnotation
        var anotacionSeleccionada : MKPointAnnotation!

    func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
        if control == view.rightCalloutAccessoryView {
        anotacionSeleccionada = view.annotation as? MKPointAnnotation
        performSegue(withIdentifier: "vista", sender: self)
        }
      }


    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if let destination = segue.destination as? ViewController {
        destination.pin = anotacionSeleccionada
       }
     }

In your viewFor annotation function add this row in the beginning:

if annotation is MKUserLocation {
   return nil
}

Because you don´t want to do anything if it´s the MKUserLocation.
