iphone - Adding new entity to core data model?

Question

Is adding a new entity on the new version of my core data model going to crash the apps using the older versions of core data model?

What if this entity has a relationship with an existing entity.

oldEntity (1)------------->(oo) newEntity

Answer 1

Sounds like a simple case for versioning, which can be done quite simply in a lot of instances. This sounds like one of them.
