【问题描述】：
我在 XCode 中创建了一个空白 SwiftUI 项目，并选择包含 Core Data 和 Cloud Kit。
默认情况下，Apple 已经在项目中包含了一些 Core Data 示例代码和实体，还有一个包含 NSPersistentCloudKitContainer 代码的 Persistence.swift 文件。
（Core Data 的示例代码是将时间戳记录到 SwiftUI 列表中，例如 Apple 介绍视频的 05:18~06:10：https://developer.apple.com/videos/play/wwdc2019/202/）
经过一些基本设置后，假设应用程序的数据记录和记录类型可以显示在 Cloud Kit 仪表板的相关容器上，但它没有。
这是我所做的：
- 我按照教程https://developer.apple.com/documentation/coredata/mirroring_a_core_data_store_with_cloudkit/setting_up_core_data_with_cloudkit
- 使用 Core Data 和 Cloud Kit 创建项目
- 由于 Apple 已经设置了 Persistence.swift 文件，因此没有触及任何代码。
- 还没有触及应用结构、内容视图和核心数据实体（保持所有示例代码不变）
- 已选择自动管理签名和开发团队，并带有付费开发人员帐户。
- 添加了 iCloud 功能
- 在 iCloud 功能中选择 CloudKit，创建 CloudKit 容器。
- 添加了后台模式功能并选择了远程通知。
接着：
- 启动模拟器，启动应用程序，被要求使用 Apple ID 登录，然后就这样做了。
- 在 SwiftUI 列表中添加一些时间戳。
- 杀死应用程序并重新启动，时间戳仍然存在，甚至删除应用程序并重新安装。 Core Data 示例代码完美运行。
- 进入CloudKit Dashboard的相关容器，选择Records，Private Database，Record Type只有\"Users\"。没有显示其他记录类型。

/*
Typical reasons for an error here include:
* The parent directory does not exist, cannot be created, or disallows writing.
* The persistent store is not accessible, due to permissions or data protection when the device is locked.
* The device is out of space.
* The store could not be migrated to the current model version.
Check the error message to determine what the actual problem was.
