这是 Apple 的声明。

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.

1. 下载https://developer.apple.com/certificationauthority/AppleWWDRCA.cer 并双击安装到 Keychain。
2. 在 Keychain 应用中选择“查看”->“显示过期证书”。
3. 从 Keychain 应用的“登录”选项卡和“系统”选项卡中删除 Apple 全局开发者关系证书颁发机构的证书。

确保新下载的证书同时在登录和系统中默认为仅系统选项卡仍会出错。**
