Hi Martin,
It sound like you did not include NSPersistentStoreUbiquitousContentNameKey as
part of the options dictionary when creating your persistent store coordinator
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:uuid_string,
NSPersistentStoreUbiquitousContentNameKey, nil];
[persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType
configuration:nil
URL:storeUrl
options:nil
error:&error])
It's tricky to figure out exactly what to do. I found this Using Core Data with
iCloud Release Notes under "Guidance for Library-style Applications".
Hope this helps
