How to prevent popover scaling when keyboard appears?

Question

My iPad app has a popover with a few UITextFields at the top half.

When tapping a textfield, which makes the keyboard appear, iOS scales (and moves) my popover. I don't want that.

How do I prevent iOS from doing that?

This answer suggests to override some keyboardWillShow() and keyboardWillHide() functions, but it's unclear where these are defined.

As mentioned by Leszek in the comments update the popoverPresentationController.popoverLayoutMargins of your UIViewController to accommodate the height of the keyboard:

func configurePopoverPresentationController() {
        let keyboardHeight = 500
        popoverPresentationController.popoverLayoutMargins = UIEdgeInsets(top: 0.0, left: 0.0, bottom: -keyboardHeight, right: 0.0)
    }
