问题
My Xcode has upgraded to Version 9.3, I have more than one Apple account, it works well when I add one more account to Xcode, but only one account is left when reopening Xcode, and the Team field shows "Unknown Name XXX".
This may be caused by Keychain, and I have deleted the corresponding certificates, but the issue is still the same.
