didfailwitherror

I'm using CoreLocation to successfully determine the user's location. However when i try to use the CLLocationManagerDelegate method: func locationManager(_ manager: CLLocationManager!, didFailWithError error: NSError!) I run into problems with the error term. func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) { println("didFailWithError \(error)") if let err = error { if err.code == kCLErrorLocationUnknown { return } } } This results in a 'Use of unresolved identifier kCLErrorLocationUnknown' error message. I know that the kCLErrors are enums and that they

I haven't think of this yet now . Till now whenever device was asking me use location update I was allowing it . But when now I am not allowing then it the location manager gives me kclErrorDenied and the location manager can not start again until I restart the application . So my question is that should I give a message to restart the app to the user or is there a solution to start working the location manager again . thanks . The Error : ERROR,Time,288787555.078,Function,"void CLClientHandleDaemonDataRegistration(__CLClient*, const CLDaemonCommToClientRegistration*, const __CFDictionary*)"
