How to display a circle in GMSMapView

Question

I need to display a circle (as with MKCircle) on a GMSMapView. This is easy when using a MKMapView and MKCircle, but can\'t use MKCircle with GMSMapView. Any ideas?

Answer 1

func mapView(_ mapView: GMSMapView, didChange position: GMSCameraPosition) {
    // Make sure cicle is a GMSCircle Object  and it is a class variable
    circle.map = nil

    let point = mapView.center
    circle.position = mapView.projection.coordinate(for: point)
    circle.radius = 130.0
    circle.fillColor = .clear
    circle.strokeColor = .black
    circle.strokeWidth = 3.4
    circle.map = mapView
}
