Keeps deleting and loading store

[simonbs]

I use UbiquityStoreManager in an app that supports both iOS 7 and 6. It works perfectly on iOS 7 but when I initialize UbiquityStoreManager on iOS 6, I will keep getting the following messages:

2014-03-14 19:19:08.847 MyApp[1131:3427] UbiquityStoreManager: [DEBUG] cloudSafeForSeeding: 1

    NSInferMappingModelAutomaticallyOption = 1;
    NSMigratePersistentStoresAutomaticallyOption = 1;
    NSReadOnlyPersistentStoreOption = 1;
}

These exact messages will keep appearing.

Do you know why this happens?
