Let's say I use Core Data with entity 'Book' which has 'name', 'author', 'summary' and 'isFavorite' attributes. I prefill the Core Data and the only attribute which user can edit is 'isFavorite'. In the next version of the app for some records I want to change/correct content of the 'summary' attribute but keep content of the 'name', 'author' and - most important - 'isFavorite'. Can I somehow use Core Data versioning for that? Or the Core Data versioning is only for model and has nothing to do with content and I should I look for some other solution?

Core Data versioning affects only the model, the content doesn't matter. – vadian Jun 04 '17 at 08:51

"the only attribute which user cannot edit is 'isFavorite'." did you mean "the only attribute which user **can** edit is 'isFavorite'."? – Jon Rose Jun 04 '17 at 09:53
