Answer 1

Swift:

In viewDidAppear(otherwise elements are not yet layered) of your ViewController:

        var yourFrame = yourScrollView.convertRect(yourScrollView.frame, to: self.view)

        //PRINT THE WHOLE RECT
        print(yourFrame)

        //PRINT A DETAILED VERSION OF THE FRAME, ALSO CAN PERFORM CALCULATION BETWEEN THE RECT PARAMETERS TO GET , FOR EXAMPLE, WIDTH POINT IN THE SUPERVIEW:
        print("X: \(yourFrame.origin.x) Y: \(yourFrame.origin.y) WIDTH: \(yourFrame.width) HEIGHT: \(yourFrame.height)")
