Hi thanks for the reply,
starting with the assumption that it's simpler if the view controller hierarchy does not change based on changes in size class... as vertical space is shorter on the iPhone Duo vs a standard iPhone, I think it's reasonable to hide one of the vertical sections in the layout (where the infomation is supplementary to the main section) on the iPhone Duo, if the user want's to see it they can unfold to the large display. I suppose the other approach is to return a different layout rather than to adapt in in the sectionProvider based on sizeClass, but then it would probably require manual invalidation (sorry just thinking out loud).
