I'm trying to create a lib with cocoapods, but I have a problem.
I have no prestige for the moment. If you want to help me, you can open the next image.

A cocoapods lib of local

When I tried to use coredata, re-installed cocoapods. That project doesn't have coredata.xcdatamodeld file.
I find this resolve func, but don't resolve this problem.
