I knew that modifying core-data previous version breaks the light-weight migration. But I have inverse relationship warnings on old versions of data model.
I tried removing old versions that are used before launching first version of our app. I followed this SO question, "How to delete an old/unused Data Model Version in xCode 4"
- It removes warning(Of course it should)
- But I cannot run our app anymore
I think I should keep every versions even though it is not related to light-weight migration
I saw this SO question, "How to disable no inverse relationship warning for CoreData in Xcode 4.2?". And I tried setting the MOMC_NO_INVERSE_RELATIONSHIP_WARNINGS to YES.
- It doesn't removes warning
- And I don't want my future mistake, missing inverse setting, also be ignored.
I think this option is not for my case
I don't want to see compiler warning for old version of data model(.xcdatamodel). Because these models are not used so that warnings are not significant.
But I want to see future inverse relationship warning on newer version of data model.
What option can I take?
