Hi taehunchoi,

Thanks for using the Zoom SDK. It looks like the SDK init and auth was successful. When joining a meeting, the app crashes. Are you using UIScene? Could you have a try and see if you could get this crash with our iOS SDK demo app? If so, what are the steps to reproduce this with our demo app?

Thanks!

Hi Carson,

Yes Xcode version 11.
and i just found out that zoom sdk does not support Xcode 11.

Hi taehunchoi,

Yes, our SDK does not support Xcode 11 at the moment. Xcode 11 introduced a lot of new components: UIScene, dark mode, etc., we are working to support it. Please have a try to remove the components that are unique/new in Xcode 11 and see if that helps.

Thanks!
