It turned out that Xcode has signed me out from my apple ID account.
结果是 Xcode 从我的 Apple ID 帐户中注销了我。
So I went to
所以我去了
Xcode -> Preference -> Accounts
and re-logged into my account again.
并再次重新登录我的帐户。
and now the error is gone
现在错误消失了

You can check if Apple's systems are currently under maintenance by visiting: https://developer.apple.com/system-status/
您可以访问：https: //developer.apple.com/system-status/查看 Apple 的系统当前是否在维护中

If everything is fine with https://developer.apple.com/system-status/the problem might be when you have low space on disk where is macOS and Xcode. Had the same problem, did remove some unused apps to free some space and after restarting Mac everything started working again.
如果https://developer.apple.com/system-status/一切正常，问题可能出在 macOS 和 Xcode 所在的磁盘空间不足时。遇到了同样的问题，确实删除了一些未使用的应用程序以释放一些空间，并且在重新启动 Mac 后一切又开始工作了。
