I am getting the following error on my project and I am not sure what is causing it.



2017-04-04 10:28:39.243789-0500 GBus3[797:148184] libMobileGestalt 
MobileGestaltSupport.m:153: pid 797 (GBus3) does not have sandbox access for
frZQaeyWLUvLjeuEK43hmg and IS NOT appropriately entitled
2017-04-04 10:28:39.243948-0500 GBus3[797:148184] libMobileGestalt
MobileGestalt.c:550: no access to InverseDeviceID (see
<rdar://problem/11744455>)
fatal error: unexpectedly found nil while unwrapping an Optional value
2017-04-04 10:28:43.106075-0500 GBus3[797:148184] fatal error: unexpectedly
found nil while unwrapping an Optional value


I believe the error occurs when using a segue to switch between view controllers.



this is the code to execute the segue



func didTapTrackButton () {

performSegue(withIdentifier: "HomeToTrack", sender: self)
}


This is the code for loading the second view controller



override func loadView() {
super.loadView()
// Building a view
let screenFrame = UIScreen.main.bounds
let contentView = UIView(frame: screenFrame)

// Add Map
self.mapView = MKMapView(frame: screenFrame)
self.mapView.delegate = self
contentView.addSubview(self.mapView)

// Set Tracking
self.locationManager.delegate = self
self.locationManager.requestAlwaysAuthorization()
self.mapView.setUserTrackingMode(MKUserTrackingMode.follow, animated: true)

// Set the built view as our view
self.view = contentView
}

  • The compiler does not say where the error occurs. After using breakpoints I found it is when there is a switch between view controllers, which I have added

  • Oddly enough this exact same message started showing up in the output for our app - assuming it has something to do with 10.3.1. We're presenting a UIWebView with NSData as the source in a dispatch_async. No idea (yet) which of these are responsible for the log entry

  • I also see this error, (first 2 lines of your log) in a scenekit app on 10.3.1 . Looks like Apple did not update their own libraries, and it's not caused by any user code. The third one, your fatal error, I don't get.
