iCloud e dati di base - "Il percorso è all'esterno di qualsiasi contenitore CloudDocs, non verrà mai sincronizzato"

Question

Così ho cercato di sincronizzare i dati tra due iDevice utilizzando Core Data & iCloud per alcune settimane. Il numero documentation di Apple del 2012/2013 è scritto in Objective-C e non è molto dettagliato.

Ho provato a convertirlo in Swift 2.0 per iOS9. Per prima cosa ho pensato che avrei potuto realizzarlo, due dispositivi in ​​cui condividere i dati e sincronizzare le eventuali modifiche. Poi le cose sono diventate disordinate, i dati che erano stati precedentemente cancellati hanno iniziato a comparire e l'unico modo per sincronizzare è quello di rilanciare l'app. Ora sono stato colpito con questo errore:

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"

Se continuo a correre l'applicazione tramite Xcode (7) che sembra correggere se stesso e le modifiche di sincronizzazione, ma questo non è l'ideale per il mondo reale; gli utenti non devono forzare la chiusura di un'app e il riavvio della sincronizzazione, e se i dati sono corrotti, quindi reinstallare.

Qualcuno ha qualche idea in cui potrei sbagliare e perché si sta verificando questo errore?

Answer 1

Ho avuto lo stesso problema prima. Ho passato mezza giornata a controllare il codice e ho scoperto che ho usato il nome del contenitore iCloud sbagliato. Avevo un'app in ambiente di sviluppo, il cui nome è molto simile a quello in ambiente di produzione.
