iCloud & Core Data - "Pfad befindet sich außerhalb eines beliebigen CloudDocs Containers, wird nie synchronisiert"

Question

Also habe ich versucht, Daten zwischen zwei iDevices mit Core Data & iCloud für ein paar Wochen zu synchronisieren. Apples documentation aus 2012/2013 ist in Objective-C geschrieben und ist nicht sehr detailliert.

Ich habe versucht, es in Swift 2.0 für iOS9 zu konvertieren. Zuerst dachte ich, ich hätte es geschafft, zwei Geräte, wo Daten geteilt und Änderungen synchronisiert wurden. Dann wurden die Dinge unordentlich, Daten, die zuvor gelöscht worden waren, begannen zu erscheinen und die einzige Möglichkeit zur Synchronisierung ist ein Neustart der App. Jetzt habe ich mit diesem Fehler betroffen:

CoreData: Ubiquity: Librarian returned a serious error for starting downloads Error Domain=BRCloudDocsErrorDomain Code=6 "Path is outside of any CloudDocs container, will never sync"

Wenn ich halten Sie die App über Xcode läuft (7) es scheint selbst und Sync-Änderungen zu beheben, aber das ist nicht ideal für die reale Welt; Benutzer sollten nicht gezwungen werden, eine App zu beenden und die Synchronisierung neu zu starten. Wenn die Daten beschädigt sind, installieren Sie sie neu.

Hat jemand irgendwelche Ideen, wo ich falsch liegen kann und warum dieser Fehler auftritt?

Answer 1

ich vor demselben Problem hatte. Ich habe einen halben Tag damit verbracht, den Code zu überprüfen, und es stellte sich heraus, dass ich den falschen iCloud-Containernamen verwendete. Ich hatte eine App in der Entwicklungsumgebung, deren Name dem in der Produktionsumgebung sehr ähnlich ist.
