iCloud & Core Data - «Путь находится за пределами любого контейнера CloudDocs, никогда не синхронизируется»

Question

Итак, я пытаюсь синхронизировать данные между двумя iDevices, используя Core Data & iCloud в течение нескольких недель. Apple documentation от 2012/2013 написан в Objective-C и не очень подробный.

Я попытался преобразовать его в Swift 2.0 для iOS9. Сначала я подумал, что, возможно, это выполнил, два устройства, в которых используются данные и синхронизация любых изменений. Затем все стало беспорядочно, данные, которые ранее были удалены, начали появляться, и единственный способ синхронизации - перезапустить приложение. Теперь я был поражен с этой ошибкой:

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"

Если я продолжать работать приложение через Xcode (7) он, кажется, исправить себя и изменения синхронизации, но это не является идеальным для реального мира; пользователи не должны вынуждать покидать приложение и перезапускать синхронизацию, а если данные повреждены, то переустановите.

Есть ли у кого-нибудь идеи, где я могу ошибиться и почему эта ошибка возникает?

Answer 1

я до этого был такой же вопрос. Я провел половину дня, чтобы проверить код, и оказалось, что я использовал неправильное имя контейнера iCloud. У меня было приложение в среде разработки, имя которого очень похоже на одно в рабочей среде.
