ios - 为什么我无法从 Xcode 或 CloudKit Dashboard 查询 CloudKit？

Question

当我尝试从 CloudKit Dashboard 查询 CloudKit 时，收到一条错误消息:

There was a problem querying the “Entry” type.

no auth method found

当我尝试从 Xcode 中的代码查询相同的记录时，我从查询操作的 queryCompletionBlock 属性中的错误对象中收到错误消息:

The operation couldn’t be completed. (CKErrorDomain error 4.)

在哪里可以找到错误 4 的含义？

以下是在调试窗口中打印错误消息的代码:

let predicate = NSPredicate(value: true)
let query = CKQuery(recordType: DatabaseNameStrings.recordTypeEntry, predicate: predicate) // DatabaseNameStrings.recordTypeEntry = "Entry"
let sortDescriptor = NSSortDescriptor(key: DatabaseNameStrings.recordFieldKeyCreationDate, ascending: true)
query.sortDescriptors = [sortDescriptor]
let queryOperation = CKQueryOperation(query: query)
queryOperation.database = container.privateCloudDatabase
queryOperation.desiredKeys = [DatabaseNameStrings.fieldNameText] // DatabaseNameStrings.fieldNameText = "text"
queryOperation.recordFetchedBlock = {
    (record: CKRecord) in
    let entry = Entry(ckRecord: record)
    self.entries.append(entry)
}
queryOperation.queryCompletionBlock = {
    (cursor: CKQueryOperation.Cursor?, error: Error?) in
    if let error = error {
        print(error.localizedDescription) // The operation couldn’t be completed. (CKErrorDomain error 4.)
    } else {
        DispatchQueue.main.async {
            self.tableView.reloadData()
        }
        if let cursor = cursor {
            let innerQueryOperation = CKQueryOperation(cursor: cursor)
            innerQueryOperation.desiredKeys = queryOperation.desiredKeys
            innerQueryOperation.recordFetchedBlock = queryOperation.recordFetchedBlock
            innerQueryOperation.queryCompletionBlock = queryOperation.queryCompletionBlock
            queryOperationQueue.addOperation(queryOperation)
        } else {
            DispatchQueue.main.async {
                self.tableView.reloadData()
            }
        }
    }
}
queryOperationQueue.addOperation(queryOperation)

它开始工作，但我没有做任何事情来修复它。
