How to display a Google Maps info window on the right side in iOS

Question

I would like to display a custom infoWindow to the right of the marker that has been tapped.

Per default, the info window is displayed at the top of the info window with

let anchorPoint = CGPointMake(0.5, 0.0).

In order to display my info window at the right side, I have to anchor it to the right bottom of my marker. So I changed the info window anchor point like this:

func mapView(mapView: GMSMapView!, markerInfoWindow marker: GMSMarker!) -> UIView! { 

    //load info window from xib
    //let infoView = ...
    let infoWindowAnchor = marker.infoWindowAnchor
    let newAnchor = CGPointMake(1.0, 1.0)
    marker.infoWindowAnchor = newAnchor
    //...

    return infoView       
}

But since the info window's bottom is centered around the marker's anchor point, I have to increase the info markers x position by 0.5 * infoMarker.width and readjust the camera if neccessary. I have no clue how to do this.

Basically I'm looking for the iOS way of adding an offset to the info window (comparable to pixelOffset in the JS API).

Setting up infoWindowanchor at any point can work for example while creating marker(if infowindow is of same size for all) Following worked for me:

        let marker1 = GMSMarker()
        marker1.position = coordinatesLocationOne
        marker1.title = "US"
        marker1.snippet = "US"
        marker1.infoWindowAnchor = CGPoint(x: 2.5, y: 2.5)
