Hi @ddev, Thanks for the post. Are you using UIScene? Is this reproducible with our demo app? If so, could you provide the steps to reproduce this with our demo app? Thanks! ---

I am using UIScene. Are you saying the framework should work with UIScene? ---

Hi @ddev, Our iOS SDK does not Xcode 11 at the moment(Even if you could compile using Xcode 11, but those new features like UIScene, Swift UI, dark mode, etc. are not supported) Please try not to use UIScene at the moment and see if the crash persisits. Thanks! ---

That’s unfortunate. UIScene has been out for a long time. We can’t switch back to the old way… Until zoom supports UIScene we won’t be able to integrate with zoom. SwiftUi and all other features don’t matter to us. It would be nice if the SDK would simply accept a parent ViewController instead of messing with the window etc… We’ll stay tuned and hopefully UIScene support will happen soon. 🤞 Thank you ---

Hi @ddev, Thanks for the reply. I understand. I will forward your feedback to the engineering team. Pardon the inconvenience caused by this. Thanks! ---

Is there any update on this crash? iOS 14 beta is almost here… apps have updated to UIScene a long time ago. We would love to be able to run zoom SDK on UIScene apps… Thank you ---

Hi @ddev, Thanks for the reply. Unfortunately, I do not have any updates on this at the moment. We have dependencies on this so it takes a longer time. Thanks! ---
