CoreMotion apparently calls UI API from background thread












5















At some point in my app I am initializing a CMMotionManager. This happens on the main thread. After doing so, the Xcode 10 main thread checker indicates that



-[UIApplication applicationState] 


is not being called from the main thread. Indeed it is coming from



Thread name: com.apple.CoreMotion.MotionThread


Since this is Apple's private framework it appears to me that I just have to wait until this issue is fixed on Apple's side. Am I correct and/or is there any way to remedy this issue without switching off the main thread checker?

          Its currently a bug in the API, something is triggering in background thread.



          i could stop it with



          lazy var motionManager = CMMotionManager()


          see also https://github.com/JonasGessner/JGProgressHUD/issues/98, but there is no solution right now.

            The lazy call will only postpone the exception.
