I Found answer for my problem,, actually we can track location update even after app get terminated.
NOTE : only with some circumstances we can track location, as after app get terminated or suspended by user.
location get tracked and been indicated in status bar with indication , only when new location get recognised by device after 500 m from current location.
var locationManager: CLLocationManager?
locationManager = CLLocationManager()
locationManager?.startMonitoringSignificantLocationChanges()
