Hide Google Map info window when map is moved with Swift

Question

So with my app, I'm displaying a custom info window on a GMS Marker. This info window takes up the top half of the screen and I don't want it moving with the Marker. So I want to hide the info window as soon as the map has moved. How can I do this?

You could make your UIViewController conform to GMSMapViewDelegate and then implement one of the methods listed here: https://developers.google.com/maps/documentation/ios-sdk/reference/protocol_g_m_s_map_view_delegate-p
I guess the first one (mapView:willMove:) would work for you. I would use a print statement (or breakpoint) to check, whether the method is triggered as expected. To hide the current info window, you should be able to set mapView.selectedMarker = nil.
To sum up, your code might look like this:

import UIKit
import GoogleMaps

class ViewController: UIViewController {
    
    //declare your map, etc.
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // setup your map
    }
}

extension ViewController: GMSMapViewDelegate {
    func mapView(_ mapView: GMSMapView, willMove gesture: Bool) {
        if gesture { //The map was moved by the user
            //mapView.selectedMarker = nil
        }
    }
}
