I have a new model which syncs to cloudkit. I'have to migrate my old core data store which is local to the new model which will store in cloudkit. I'm not sure how to perform this migration. The container is initialised correctly and the Mapping Model is mapping my entities and attributes correctly. There are no errors.
Yet, I do not see my old records upon fetching. I found this lines of code here...
NSDictionary *optionsDictionary = [[NSDictionary alloc] initWithObjectsAndKeys:
[NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption,
[NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
<#Ubiquitous content name#>, NSPersistentStoreUbiquitousContentNameKey, nil];
However, I'm not sure where to add it.
Since, I had created a new project folder with core data + CloudKit (and imported the old model), this is the method i got in AppDelegate which initialises the store...
- (NSPersistentCloudKitContainer *)persistentContainer {
// The persistent container for the application. This implementation creates and returns a container, having loaded the store for the application to it.
@synchronized (self) {
if (_persistentContainer == nil) {
_persistentContainer = [[NSPersistentCloudKitContainer alloc] initWithName:@"Expenses"];
[_persistentContainer loadPersistentStoresWithCompletionHandler:^(NSPersistentStoreDescription *storeDescription, NSError *error) {
if (error != nil) {
NSLog(@"Unresolved error %@, %@", error, error.userInfo);
abort();
}
else
#ifdef DEBUG
NSLog(@"Store successfully initialized");
#endif
}];
}
}
return _persistentContainer;
}
Please help, Thanks.
