There wasn't much to improve in depth mapping, so I ended up moving to the new Xcode 8 Core Data models, and found an bug related to using hyp_dictionary.
The issue was in reserved attributes such as description and the entity OrderedUser. It was exporting ordered_user_description instead of just description.
