Background/issue: I have a Core Data app in production and I just sent out an update where I added a couple of attributes in an existing entity without making a new model version (I didn't know this was a step). This is causing my user's apps to crash. The crash only happens when they first open the app after updating then it seems to work fine after the initial crash.
How I think it can be fixed: I'm thinking that I should go to a previous commit > copy the old data model > go back to master > delete the updated data model > drag and drop the copy into Xcode > then go to Editor to "Add Model Version". After add the new attributes I need I'm scared to do this and submit it to the App Store as it may cause more problems for people who already updated their app.
Ask: Is there a way I can revert my changes to the old data model version then make a new one from that? Without affecting my current users who already upgraded to the database version with errors?
I paused the phased release of this update to stop having users get crashes so if anyone knows how to fix this please help!
