Dynamically change size of UIViewRepresentable

I have a UIView embedded in a UIViewRepresentable. I need this view to be movable and resizable. I can get it to move, but not resize, inasmuch as its frame size changes, but it isn't redrawn at the new size. I need some way for the view to communicate the size change to its SwiftUI container and for that to redraw it. Any suggestions?
