CloudKit-无法从iCloud检索数据

Question

Is there any difference in sending and receiving data from iCloud via CloudKit when the application (iOS9) runs through Xcode or when it is downloaded from the App Store?

My problem is: Application launched from Xcode receives and displays data successfully, the same app published in the App Store can not display the data...

In what could be the mistake?

Thank you.

func getRecordsFromCloud() {
        // Fetch data using Convenience API
        let cloudContainer = CKContainer.defaultContainer()
        let publicDatabase = cloudContainer.publicCloudDatabase
        let predicate = NSPredicate(value: true)
        let query = CKQuery(recordType: "Pivo", predicate: predicate)
        query.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]

        // Create the query operation with the query
        let queryOperation = CKQueryOperation(query: query)
        queryOperation.desiredKeys = ["name", "type", "location"]
        queryOperation.queuePriority = .VeryHigh
        queryOperation.resultsLimit = 50
        queryOperation.recordFetchedBlock = { (record:CKRecord!) -> Void in
            if let restaurantRecord = record {
                self.restaurants.append(restaurantRecord)
            }
        }

        queryOperation.queryCompletionBlock = { (cursor:CKQueryCursor?, error:NSError?) -> Void in
            if (error != nil) {
                print("Failed to get data from iCloud - \(error!.localizedDescription)")
                return
            }

            print("Successfully retrieve the data from iCloud")
            self.refreshControl?.endRefreshing()
            NSOperationQueue.mainQueue().addOperationWithBlock() {
                self.spinner.stopAnimating()
                self.tableView.reloadData()
            }

        }

        // Execute the query
        publicDatabase.addOperation(queryOperation)
    }
