NOTE: this only seems to be a problem since 8.3.
I have a split view controller. For easy of explanation I created a brand new master/detail project in xcode (6.3). I changed the master view to be a tab bar.
Simply just removed the TableViewController that was part of the default project, drug in a TabBarController and added it as the master view controller relationship.
When running I get the following error:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle (loaded)' with name 'z2L-Ml-BPJ-view-fno-cZ-fCP''
If I run in 8.1 it runs just fine. I have no idea how to workaround this in 8.3
