Swift — добавление постоянного хранилища с поддержкой iCloud в основные данные

var appDel:AppDelegate = (UIApplication.sharedApplication().delegate as AppDelegate)
let documentsDirectory:NSURL = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as NSURL
let storeUrl:NSURL = documentsDirectory.URLByAppendingPathComponent("CoreData.sqlite")
var error:NSError?
let coordinator:NSPersistentStoreCoordinator = NSPersistentStoreCoordinator(managedObjectModel: appDel.managedObjectModel)
let storeOptions:NSDictionary = [NSPersistentStoreUbiquitousContentNameKey:"MyAppCloudStore"]
let store:NSPersistentStore = coordinator.addPersistentStoreWithType("NSSQLiteStoreType", configuration: nil, URL: storeUrl, options: storeOptions, error: &error)!
let finaliCloudURL = store.URL

Это приносит мне ошибку:

} ... returned error Error Domain=NSCocoaErrorDomain Code=134080 "The NSSQLiteStoreType persistent store type does not support iCloud integration."

Я включил iCloud в разделе «Возможности со службами: хранилище ключей и значений».
