App crashed when change CoreData properties

[Pavel Volobuev]

Hello everyone,
I used CoreData database in my App.
Now i want to update my app and I changed something in CoreData model file (AppName.xcdatamodeld)
After that my app crashing after start. I think, this occurs due to incompatibility CoreData models in Apps. How can I solve this problems?

Any ideas?

Look up apples docs for entity migration and core data versioning. You can't change the schema but a tiny amount without migration
