Scale UIView with the top center as the anchor point?

I'm scaling a UIView with CGAffineTransformMakeScale but I want to keep it anchored to it's current top center point as it's scaled.

I've looked into setting view.layer.anchorPoint but I believe I need to use this in conjunction with setting view.layer.position to account for the change in the anchor point.

If anyone could point me in the right direction I'd be very grateful!
