Do I need to do anything else than the following when switching camera to guard against crashes:

• (void)changeCamera { switch (_session.cameraState) { case VCCameraStateFront: _session.cameraState = VCCameraStateBack; break;

  case VCCameraStateBack:
    _session.cameraState = VCCameraStateFront;
    break;
  
  default:
    break;

  } }

That crash doesn't appear to have anything to do with the camera, so it's curious that it happens when flipping the camera....
