ILocationService

Best currently known geoposition. If there is no currently known geoposition, nil is returned. The geoposition returned by this method may not be valid. This method must request the best currently known geoposition from the system and return it even if it is outdated and/or does not meet the required accuracy. If the platform API does not provide a method with similar functionality, this method will always return nil.
See the CLLocationManager.location method.
