I am using the Whirly Globe Component in an app I'm developing. In that app , there is an option for our users to add a marker on the map at a specific location  (so that a user can drag the map to a specific location and place a Pin on the center of the screen). That pin would allow us to retrieve GPS latitude , longitude coordinates (to interact with the rest of the app).   At this point I can  i am not able to get the latitude and longitude, I can only get X and Y coordinates from the map.  Please check at the Following codes   - (void)globeViewController:(WhirlyGlobeViewController *)viewC didTapAt:(MaplyCoordinate)coord {     NSLog(@"tab");     NSLog(@"You tapped at %f,%f", coord.x, coord.y);     }
