Thank you OOPer! I didn't realize the #available is so special, such that there is no other "#Name" kind of conditions.

Hi OOPer, My project does not have an automatically generated SceneDelegate.swift. I remember when the iOS13 was the newest iOS version, SceneDelegate.swift is automatically generated when I create a project, but for newer version (after iOS14) of Xcode, both SceneDelegate.swift and AppDelegate.swift are no longer automatically generated. I was able to add a an AppDelegate.swift file to the project, but don't know how to add SceneDelegate.swift. As long as there is a way for me to get the UIViewControl object that is being display on the phone, I think passing it into the SDK function will make it display the proper dialog. By the way, I followed the following link to add the AppDelegate.swift, but wasn't able to find a similar method for SceneDelegate.swift www .hackingwithswift.com/quick-start/swiftui/how-to-add-an-appdelegate-to-a-swiftui-app

I made a typo, it should be the 4th link...
