这是证书重复的错误，需要将钥匙串里重复的证书删掉编译才能通过。但是，如果你重启Xcode ，会发现之前删除的证书又回来了。但当重新启动Xcode时，Xcode里的证书会被导进钥匙串，所以仅仅是删除钥匙串中重复证书是无效的。
相信许多同学对 Xcode 的这个 Bug 深恶痛绝了，但除了反复地（但是徒劳地）从钥匙串中删除证书，也没有别的办法。
其实，也不能光怪 Xcode，而是跟”iPhone 配置使用工具“也有一定的关系。
Xcode中的这些“残留”证书不以常规的形式存在。如果你安装了“iPhone 配置实用工具”，这些证书实际上存在于/Users/yourname/Library/MobileDevice/Applications/目录下的.app 文件中，这些.app 实际上是 “iPhone配置实用工具”——“应用程序”中的所导入的 app。你可以用Finder ——“显示包内容”来查看.app 。其中一个名叫“embedded.mobileprovision”的文件，就是“残留”的重复证书。你可以逐一删除这些 .app，也可以干脆把该目录下的所有.app 都删除（反正只要项目文件存在，你随时可以编译出这些 .app并导入到“iPhone 配置实用工具”中）。最后，还要将 Orgnizer 中的重复证书也删除，然后重启Xcode。
