CLLocationManager kCLErrorDomain Codes?

Question

Using iBeacon and CoreLocation I'm receiving the following error:

Error Domain=kCLErrorDomain Code=16 "The operation couldn’t be completed. (kCLErrorDomain error 16.)

Unless I'm missing it, there doesn't seem to be a clear reference on Apple for what each of the error code means.

Can anyone interpret this error code?

The error calls from:

- (void)locationManager:(CLLocationManager *)manager rangingBeaconsDidFailForRegion:    (CLBeaconRegion *)region withError:(NSError *)error{
NSLog(@"%@", error);
}

- (void)locationManager:(CLLocationManager *)manager monitoringDidFailForRegion:(CLRegion *)region withError:(NSError *)error{
NSLog(@"%@", error); }

Answer 1

Look at the docs for CLError. Value 16 is kCLErrorRangingUnavailable.

The docs say:

Ranging is disabled. This might happen if the device is in Airplane mode or if Bluetooth or location services are disabled.

Answer 2

You can use the CLError enum and the error returned to your location manager to handle location errors in a specific and clear way.

It looks like this:

func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
  if let locationError = CLError(rawValue: error.code) {
    switch locationError {
    case .Denied:
      println("Location permissions denied")
    default:
      println("Unhandled error with location: \(error)")
    }
  }
}

Thanks to @rmaddy for the CLError tip.
