Test if MapKit is using Apple data or AutoNavi data

MapKit-autonavi.swift

let geocoder = CLGeocoder()
let appleHQCoord = CLLocation(latitude: 37.331998, longitude: -122.029645)
geocoder.reverseGeocodeLocation(appleHQCoord) { (placemarks, error) in
    
    if (error?.code == 2) {
        // using autonavi
    }
    else {
        // using apple map    
    }
}
