New SDKs and Xcode 26 beta 2 just dropped.
Well, maybe not.

Got the beta 2 SDK after a few tries. Looks like there aren't any changes for Liquid Glass in UIViews:

1) The cornerConfiguration API is still MIA

2) Setting the UIVisualEffectView's effect property to nil doesn't remove the glass effect.

Workarounds are still to use the layer.cornerRadius and alpha on stuff to make it look/work reasonably.

@chockenberry cornerConfiguration is still missing from beta 3, and the layer cornerRadius workaround no longer appears to work
@tomhamming I just discovered the same thing.
@chockenberry Setting UIVisualEffectView's effect property to nil still doesn't seem to work to animate the view away in beta 5. That everyone else's experience too?
