Swift 5: How to add Marker on GoogleMap on tap/touch with coordinates?

I was learning GoogleMap-SDK for iOS, in the process i did searched for the above question and found satisfactory answers but not the one that's practically useful.

E.G. : Swift 3 google map add markers on touch

It adds Marker but does not have Place Name or Place Details and without that Marker is not that useful and for that i have to search other answers to get Address from the coordinates.

So , here i have combined both answers to save time of fellow developers and make it Marker more practical.

For Swift 5.0+

First, make sure you have added GMSMapViewDelegate delegate to your ViewController Class

We do not need UILongPressGestureRecognizer or UITapGestureRecognizer for this, GMSMapViewDelegate provides convenient default method for this.

///This default function fetches the coordinates on long-press on `GoogleMapView`
func mapView(_ mapView: GMSMapView, didLongPressAt coordinate: CLLocationCoordinate2D) {
     
     //Creating Marker
     let marker = GMSMarker(position: coordinate)
    
     let decoder = CLGeocoder()

     //This method is used to get location details from coordinates
     decoder.reverseGeocodeLocation(CLLocation(latitude: coordinate.latitude, longitude: coordinate.longitude)) { placemarks, err in
        if let placeMark = placemarks?.first {

            let placeName = placeMark.name ?? placeMark.subThoroughfare ?? placeMark.thoroughfare!   ///Title of Marker
            //Formatting for Marker Snippet/Subtitle       
            var address : String! = ""
            if let subLocality = placeMark.subLocality ?? placeMark.name {
                address.append(subLocality)
                address.append(", ")
            }
            if let city = placeMark.locality ?? placeMark.subAdministrativeArea {
                address.append(city)
                address.append(", ")
            }
            if let state = placeMark.administrativeArea, let country = placeMark.country {
                address.append(state)
                address.append(", ")
                address.append(country)
            }

            // Adding Marker Details
            marker.title = placeName
            marker.snippet = address
            marker.appearAnimation = .pop
            marker.map = mapView
        }
    }
}

HOPE IT HELPS !!!
