Height of Text view, VStacks/HStacks of Text views

Is there a way to calculate what the height of a VStack of Text views would be if added to a view, but to do so without necessarily adding it?

I am trying to figure out if I need to use NSAttributedString code to calculate formatted string heights.

Thanks.
