引起这个错误的原因是由于"Apple Worldwide Developer Relations Certification Intermediate Certificate"过期了。这需要下载新的证书安装，并删除旧的证书就可以解决该问题
需要注意的是：在『登录』和『系统』中都有该证书，需要都删了，才可以。
苹果官方说明：
The previous Apple Worldwide Developer Relations Certification Intermediate Certificate expired on February 14, 2016 and the renewed certificate must now be used when signing Apple Wallet Passes, push packages for Safari Push Notifications, Safari Extensions, and submissions to the App Store, Mac App Store, and App Store for Apple TV.
