I am coding a new version of my app and it has a new store version. I add a new version of the model and set the Model version of the new model in the Inspector view of the model.

I added an options dictionary to addPersistentStoreWithType (as explained in the documentation of Lightweight migration)...

NSDictionary *options = @{NSMigratePersistentStoresAutomaticallyOption: @YES, NSInferMappingModelAutomaticallyOption: @YES};

But I am receiving the following error...

Error Domain=NSCocoaErrorDomain Code=134100 "The managed object model version used to open the persistent store is incompatible with the one that was used to create the persistent store.

Please suggest what I should do.

Yes. Just few attributes were added. The problem has been rectified. Turns out i added the migration options in the line of code which adds a persistent store for core data with icloud (old code) instead of a local store.

Have you verified that the changes you made to the object model fall within the limitations of lightweight migration?
