CoreData versioning - how often do I need to add version?
Let's say I create a new version of my model today and I add some properties to my model. In a couple of days I need to add a few more properties, do I then need to create another version of my model? For each individual change?
While developing I would not recommend to add a new version for each change. You would end up with far to many versions soon.
Creating a new version for each public release of your software should be sufficient in most cases.
