How would I create an UIView / UILabel with vertical text flow which would look like the red view of this example screen?

I have read about view.transform = CGAffineTransform(... which allows for easy rotation, BUT it would break the auto-layout constraints.

I would be happy to use a third-party library, but I cannot find any.
