I have an iPhone app up on the store which uses core data. Now, every time I change something in my code with relation to core data, namely my managedobjectmodel or my model classes, I have to wipe all my data since I get a persistent store error.
Now I’m finding i need to make changes to my app and I don’t want my users to lose all their data. What do I do? This is my first foray into Core Data so any help is appreciated. Thanks.
Never mind. It’s versioning and migration that I need to look into, no bother.
