        I'm using CoreData with iCloud and an NSFetchedResultsController for data preperation for the UITableView.


        I have the following problem.

        During initial App launch core data starts with the fallback store and the changes to the iCloud store. When this is completed the NSPersistentStoreCoordinatorStoresDidChangeNotification fires.

        My problem now is that my NSFetchedResultsController is still reciving results from the old fallback store. Why is that?

        The only solution I have found until now is to re-init the NSFetchedResultsController with the new persisitenStoreCoordinator.


        Is there a better solution then this, because i want to use the coordinator with a lazy var like

        lazy var fetchedResultsController: NSFetchedResultsController = {

                let fetchRequest = NSFetchRequest(entityName: "Note")

                let primarySortDescriptor = NSSortDescriptor(key: "creationDate", ascending: true)

                fetchRequest.sortDescriptors = [primarySortDescriptor]

                fetchRequest.predicate = NSPredicate(format: "notebook = %@", self.selectetNotebook)


                let frc = NSFetchedResultsController(

                    fetchRequest: fetchRequest,

                    managedObjectContext: self.coreDataManager.managedObjectContext,

                    sectionNameKeyPath: nil,

                    cacheName: nil)


                frc.delegate = self


                return frc



        As far as i know there is no way to re-initialize a lazy var. Is that correct?


        Any help and suggestions are welcome
