Swift: how to find out the top right and bottom left coordinates of a google map

I need to know the top right and bottom coordinates on the left of the google map every time the camera moves. The API gives me the center point of the camera. Is there a way to get what I want using the API or using some algorithm that knows the center point (target), scaling and bearing?

func mapView(mapView: GMSMapView, didChangeCameraPosition position: GMSCameraPosition) {
    position.target
    position.zoom
    position.bearing

}

Use the GMSProjection method visibleRegion .

let projection = mapView.projection.visibleRegion()

let topLeftCorner: CLLocationCoordinate2D = projection.farLeft
let topRightCorner: CLLocationCoordinate2D = projection.farRight
let bottomLeftCorner: CLLocationCoordinate2D = projection.nearLeft
let bottomRightCorner: CLLocationCoordinate2D = projection.nearRight
