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

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

}

  • 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.

SQL update select statement
