Is it possible to present UIMenu programmatically in UIButton or UIBarButton? I have custom logic where I'd like to show that menu. I couldn't find any solution.

Apps in VisionOS can be resized by dragging a bottom right corner. But the resize mechanism is freeform (it can be resized at any width and height). How to resize the window to keep aspect ratio like it's in the native Calendar VisionOS app using UIKit?
