UISheetPresentationController with top attached views

I am using UISheetPresentationController to show bottom sheets like the one in Apple Maps. It works very well.

In Apple Maps, there is a weather indicator that sits on top of the presented sheets and follows it (to a point) when the sheet is dragged up or down. I would like to mimic this behavior for my own bottom sheets to have content from the presenting view controller stay visible while the sheet is presented.

How do I do this? Is this even possible? I think I'm looking for some kind of layout guide that sits on top of the presented sheet.

Did you find a solution to this? I'm trying to do the same thing. I can't find any delegate methods that would tell you the current height of the sheet as it is being dragged. Constraints might work to position the view above the sheet but that won't help to decide when to show/hide the view as the sheet gets higher or lower.
