Summary:
When using auto-generated methods for ordered relationship no matter Objective-C or Swift it causes app to crash in Xcode 7 beta 5 and with any other Xcode version which has these functionality of generating such methods for to-many ordered relationships. I think since Xcode 4/5.

Calling e.g. "add<Entity>Object" method ends up with:

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb) 

The only workaround for now is to re-implement those methods of my own which I would avoid.

Steps to Reproduce:
1. Open project
2. Run it.

Expected Results:
App should not crash

Actual Results:
App crashes

Version:
Xcode 7 beta 5, 10.10.4

Notes:


Configuration:
10.10.4
