经过几天的研究并感谢@Little Green Viper 的帮助，我找到了解决方案.

After days of research and thanks for the help @Little Green Viper, I found a solution.

基本上，一些Apple Worldwide Developer Relations Certification Authority 在更新后无法正常工作，但它能够为 iOS 11 成功编译.然后，最危险的解决方案是删除所有 Apple Worldwide Developer Certificates，但在此之前，请尝试在您的 Mac 上创建一个新用户.

Basically, some Apple Worldwide Developer Relations Certification Authority weren't working after the update, but it was able to compile successful for the iOS 11. Then, the most risky solution is deleting all the Apple Worldwide Developer Certificates, BUT before doing that, try creating a new user on your Mac.

(系统偏好 → 用户和组 → 新用户)应该可以工作.

(System Preferences → Users and groups → New User) that should work.

现在您必须选择、在新用户中工作或重新签署证书.就我个人而言，我选择了第一个选项.

Now you have to options, work in the new user or re-sign the certificates. In my personal case, I picked up the first option.
