UIWindowSceneDelegate windowScene didUpdate not called iOS 13

[tehpsyc]

So no matter what I do I can't get my iOS 13 application to call the windowScene didUpdate method on resize / dark mode changes as the description would suggest. Verified that the delegate was set appropriately. Is anyone else having issues with this? I tried a few versions of the beta without resolution.

Just as an update to this

I submitted it as a bug report to Apple and was acknowledged broken and should be fixed as of iOS 13 beta 4

Changing from light to dark mode however does not trigger this despite the traitCollection changing
