How to change location of my location button in google maps using swift

Update for swift 4 : just change the position of my location button only

for object in self.mapView.subviews{
            if(object.theClassName == "GMSUISettingsPaddingView"){
                for view in object.subviews{
                    if(view.theClassName == "GMSUISettingsView"){
                        for btn in view.subviews{
                            if(btn.theClassName == "GMSx_QTMButton"){
                                var frame = btn.frame
                                frame.origin.y = frame.origin.y - 100
                                btn.frame = frame

                            }
                        }
                    }
                }
            }
        }

    public extension NSObject {
    public var theClassName: String {
        return NSStringFromClass(type(of: self))
    }
}

You can change the position of the MapControls by set the padding for your map view .

 let mapView = GMSMapView()

 mapView.isMyLocationEnabled = true
 mapView.settings.myLocationButton = true

 mapView.padding = UIEdgeInsets(top: 0, left: 0, bottom: 50, right: 50)

It will change the padding of the my location control. From bottom 50px and from right 50px

Refer the below screenshot which added the padding of 50px from bottom and right.
