I posted this question here: https://devforums.apple.com/thread/77102
But maybe this is a better place.
I have a Core data model with numerous versions (xcdatamodel files) all of which are contained in the xcdatamodeld file as well as the migration schemes (xcmappingmodel files) and the header an implementation files for each entity class.
I really like how the xcdatamodeld holds all of this neatly in one file but ….
When I add the xcdatamodeld file to my Mac app only the xcdatamodeld and xcdatamodel files appear, I cannot see any of the xcmappingmodel files or header or implementation files. To make matters worse if I create new header and implementation files based on my model and try and save them to the xcdatamodeld XCode crashes.
I guess maybe the xcmappingmodel, header and implementation files should not be in the xcdatamodeld but now that they are in there how do I get them out?
Is there an app like RsrcEdit that can extract the xcmappingmodel, header and implementation files from the xcdatamodeld file?
