    Since our last app update (from Unity 2019.1 to 2019.3.11) I start seeing this crash on nearly all devices running iOS 13.3 and 13.3.1. Not a single crash on other iOS versions. Any ideas why? Only thing I can say is that it looks like a Unity bug.

    I see in the stack trace UnityViewControllerBase+iOS.mm line 62 which is related to screen edges. And one change I have made since the last update is to disable auto-rotation in the app settings and set the default orientation to "Portrait", so it may be related.

    Would making
    - (UIRectEdge)preferredScreenEdgesDeferringSystemGestures
    return
    UIEdgeRectAll
    be a valid workaround until this gets fixed?

    I don't know why the stack trace doesn't appear in the post above, here it is:

    We also have another huge amount of crashes that may be related (again dealing with screen measurements) with this stack trace:

    We're experiencing countless of crashes with this as well, did you manage to find a solution?

    ohffs apple! both stacktraces are coming from ios poking unity view/viewcontroller upon exit (sure enough it is close to impossible to catch by chance as they are usually dependent on ios version, device, showing presentation controller (ads), etc.
    the one about ViewInfo_OnDisplayCutoutsChanged - was fixed very recently (not yet released)
    UnityGetDeferSystemGesturesTopEdge - i see for the first time - can you please file a bug report (stacktrace would be enough)

    As a workaround we update the
    preferredScreenEdgesDeferringSystemGestures
    in
    UnityViewControllerBase+iOS.mm with a PostProcessBuild method. After that we experience crashes with
    prefersHomeIndicatorAutoHidden
    which we also updated.

    i did a fix for both IOSScripting::GetHideHomeButton() and IOSScripting::GetDeferSystemGesturesMode() crashes (can i whine that i didnt see the bugs reported?) and it should trickle down to LTS versions soonish

    @Alexey I'm getting the bug mentioned earlier where you get crash on exit in `ViewInfo OnDisplayCutoutsChanged `

    ...this is with the latest LTS, Unity2019.3.4, so I'm guessing the fix still hasn't been released?

    Can we get a bug number/link, so we can know which release has the fix if it's still pending?

    Also, AFAICT, there is no patch release of 2019 LTS with this fix?

    it landed week ago, so yes, most likely not yet released
    it should be out with 2019.4.5f1

    Hi all!

    So is this issue related to iOS API breaking change?
