Basically, I have a Versioned xcdatamodel
and I am migrating from V2 to V3
I created a Mapping Model
with a custom policy.
Once the PersistenStoreCoordinator
tries to do its job, I hit a Cocoa Error No. 134140 (can't find mapping model for migration)
This Question basically is the same one I'm having but I am using Xcode 4.6.3
Things I have tried:
- Forcing the
xcmappingmodel
to reside inside thexcdatamodelId
and ensuring my mapping model is not 0kb in size as per the answer of this question - Removing the
xcdatamodelId
references from Xcode and adding them back (answer of this question) - Clean and Clean Build Folder options
EDIT Here are my debug statements if anyone is interested...

The operation couldn’t be completed. (Cocoa error 134140.)
Second EDIT
I've been trying to get the Mapping Model directly by using:
NSURL *fileURL = [[NSBundle mainBundle] URLForResource:@"Update23Model" withExtension:@"cdm"];
But strangely fileURL points to nil.....
How do you add the mapping model to the bundle then?
