        I am experiencing intermittent crashes when I ran my iOS app in the simulator in the below environment MacOS 10.13.6

        Xcode Version 10.1 (10B61)

        Simulator iphone xs iOS 12.1

        Swift version 4


        Here is the error I get.



        Assertion failed: (fState == kTubeStatePostConnectConfiguration), function _onqueue_resetAndReconnect, file /BuildRoot/Library/Caches/com.apple.xbs/Sources/CFNetwork_Sim/CFNetwork-975.0.3/Connection/Establishment/Tube.cpp, line 514.


        I have seen this error intermittently with other simulators as well. Not sure how to debug these kind of errors where it crashes the app on a random thread with out knowing line causing crash.
