how to change direction of scrolling in UIScrollView?

Question

I have a horizontal scroll view with fixed height .my scroll view, scrolls from left to right but I want to scroll from Right To Left . how can I achieve this?!

this is how I created my Horizontal scroll View:

I've scroll view leading and trailing align to parent, and height = 50, inside my scroll view there is a view with equal height and width to its parent, but the priority of equal width is low, so it can scroll horizontally!

the answer was in this link I had to add these lines to my code in swift 4:

myScroll.transform = CGAffineTransform(rotationAngle: .pi);
subview.transform =  CGAffineTransform(rotationAngle: .pi);
