        Starting with iOS 13 I'm receiving error reports from users that cannot open their iCloud documents anymore. The error is each time:


            Error Domain=NSCocoaErrorDomain Code=256 "The file “Untitled.txt” couldn’t be opened." UserInfo={NSURL=file:///private/var/mobile/Library/Mobile%20Documents/iCloud~com~myapp/Documents/Untitled.txt}


        Code 256 means: NSFileReadUnknownError


        Restarting the device solves the problem each time, but I get a lot of error reports.


        My app does check the availability of iCloud documents (it uses file coordination and UIDocument). This used to work fine before iOS 13.


        Has anybody seen a similar issue? What could be causing this and how could I collect more useful debug information to get to the bottom of this?
