Size classes are not supported

[matt-oakes]

Size classes are not supported because of the way the views are removed from the containerView and then added as a subview of the view itself, before the constraints are constructed again. This process loses the size class information and leads to only the base configuration being used on all devices.

The only workaround I've found so far is to instead add the containerView as a subview of the view itself and then add constraints for the top, bottom, leading and trailing between the two. The size classes then work as expected.

Is there any other method you can think of to fix this?
