Thanks for bringing this to the attention of the community and apologies for the issues you’ve been having. This issue stems from having a copy of the expired WWDR Intermediate certificate in both your System and Login keychains. To resolve the issue, you should first download and install the new WWDR intermediate certificate (by double-clicking on the file). Next, in the Keychain Access application, select the System keychain. Make sure to select “Show Expired Certificates” in the View menu and then delete the expired version of the Apple Worldwide Developer Relations Certificate Authority Intermediate certificate (expired on February 14, 2016). Your certificates should now appear as valid in Keychain Access and be available to Xcode for submissions to the App Store.

我想我想明白了。我导入了新的WWDR证书，该证书将在2023年到期，但我仍然在构建过程中遇到问题，我的开发人员证书仍然显示无效的发行者错误。

在keychain访问方式下，执行“查看->显示过期证书”。然后在您的登录钥匙串突出显示过期的WWDR证书，并删除它。 我的系统钥匙串中也有同样过期的证书，所以我也把它删除了(这很重要)。

在从登录和系统密钥链中删除过期的证书后，我能够再次为分发版构建。

如果你从fastlane建议中得到这个错误

在尝试以上所有修复后 Security find-identity -v -p codesigning返回找到的有效身份 错误只发生在构建服务器上 如果你“手动”登录，一切正常

那么这可能是由于分发证书在错误的地方:

“登录”钥匙串在登录时工作 “系统”密钥链与构建服务器作为守护进程运行

用屏幕截图检查这个答案，你可以在登录钥匙串中右键单击分发证书，并将其粘贴到系统中。

您需要从右上角搜索栏搜索World，删除过期的证书。确保您选择了登录和所有项。
