I've found a way.

add overlay to map view in for exmple viewDidLoad: 

  if let fullRadius = CLLocationDistance(exactly: MKMapRectWorld.size.height) {

            mapView.add(MKCircle(center: mapView.centerCoordinate, radius: fullRadius))

        }

and implement delegate method:

 func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
    if overlay.isKind(of: MKCircle.self) {

        let view = MKCircleRenderer(overlay: overlay)

        view.fillColor = UIColor.blue.withAlphaComponent(0.1)

        return view
    }
    return MKOverlayRenderer(overlay: overlay)
}
