Dear list,
I seem to have messed up my core data model such that I have been sent a core data file from a user which I can't open with any of the versions of my model. I suspect I changed a model without making a new version. A bad mistake. My persistent store coordinator is set to do automatic lightweight migration, and my models haven't changed much over time.
So, I was wondering:
1) Can one determine the version of a model from it's core data store file (XML) ?
2) Can one determine the corresponding version number of the models in Xcode ?
3) Can one somehow reconstruct (if even by hand) a core data model from a store file?
Here's hoping for any bright ideas...
Martin
