Current card frame in superview coordinates

[prezessikora]

How do I get carousel current card frame in superview coordinates.

I save current card:

func carouselCurrentItemIndexDidChange(_ carousel: iCarousel) {
    currentCard = carousel.currentItemView! as! CardArtistView
}

and when clicked on card I want to know the exact position (frame) yet as I get proper width and height the origin is useless:

let currentCardFrame = currentCard.convert(currentCard.frame, to: self.view)

or

let currentCardFrame = currentCard.convert(currentCard.frame, to: carousel.contentView)

return x= 0 and y=-150 or y=-170 which is strange as the card of timemachine courses sits somewhere in the middle of screen.

Thanks!
