                print("Can't use comgooglemaps://");
            }

Here is the Swift 5 solution, where you can be sure that the map is shown in the browser if the Google Maps app is not installed or in the Google Maps app if it is installed on the device, both cases with the pin of the location.

 if UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!) {
     UIApplication.shared.open(URL(string:"comgooglemaps://?center=\(latitude),\(longitude)&zoom=14&views=traffic&q=\(latitude),\(longitude)")!, options: [:], completionHandler: nil)
 } else {
     UIApplication.shared.open(URL(string: "http://maps.google.com/maps?q=loc:\(latitude),\(longitude)&zoom=14&views=traffic&q=\(latitude),\(longitude)")!, options: [:], completionHandler: nil)
 }
