iOS Swift Parallax header using a basic UIView

Question

How can I achieve the parallax stretchy header effect using a basic UIView?. I already searched for similar question, but all I found was achieving this effect using TableView and not using regular UIView.

here's how it looks like.

I suppose this could be the hierarchy of the above app.

    ---SuperView---
      -ScrollView-
         -ImageView
         -UIView(text content)
