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.

Like Subramanian, this works very well :

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

This is perfect if you have a navigation bar in your app.

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))
    }
}
