Can it be fixed on our side? Any ideas on the root causes?


Thank you.

We are also experiencing #2, and it stands for the majority of our crashes.


We are using GameCenter through Unity and the Prime31 plugin.

I recently got a report which I believe is the same thing, on iPhone8,2; iOS 13.3.1.


And looking at the crashes for another app, there are at least 3 in -[GKNotificationBannerViewController supportedInterfaceOrientations].

Hi, we are having the same issue.
Did you found any work around?

We're hitting this issue as well. Specifically callstack #2 above.

Anyone find any work around or hack to avoid the crash even if it disables Game Center for some.

We're unable to reproduce it on any of our devices to diagnose it.

Thanks for reporting these -

For #1 and #3 please could you create bugreuports at http://bugreport.apple.com, or through the inbuilt feedback assistant, with a sysdiagnose attached and steps if you’re able to reproduce them

For #2 we believe the -[GKNotificationBannerViewController supportedInterfaceOrientations] crashes are fixed this in iOS 14 beta 1. If you continue to see this crash in that version of iOS or onwards please file again at bug report.apple.com as above
