It's unreleased - I'm still developing it - but I wrote the upgrade code and have been using it myself so I don't lose all my test data as I move from version to version. Now, as I said, all my test devices are on the latest version (all both of them) and I want to trim away the old models.
The same I guess would be true for an app where you had a number of unreleased model versions (due to development) between those you had released, you only would want to ship with the data models you had ever put into the wild, the rest is just bloat.
I can't find an Xcode sanctioned way to remove them however, that's what I'm looking for.

Looking in the versioned data model directory everything seems pretty standalone, can I just delete the models I no longer need and it will just work or is there something I can/should/need to do in Xcode to tell it to remove them? _______________________________________________
