core data - Updating an ios app that uses coredata with a version without -

we planning update ios app uses coredata complete rebuild isn't using coredata. if schema not present in update bundle crash on existing users devices?

this hard test i'm guessing schema associated app need present if isn't going used.

anyone had experience doing this?

the data model (what i'm assuming you're calling schema) needed in app if you're building core data stack. can removed if you're not building one.

you're app should still using core data time being though. you're going want build core data stack use read in user's existing data migration. if that's case, don't go deleting app yet.
