我也有同样的问题。 我换了mac。当我下载Xcode证书时，我收到了一条错误消息:“错误是安全配置文件不包括证书签名。”

1)登录https://developer.apple.com/account/ios/profile/limited/edit Select the project => edit => Certificates => Select All => Create => Download

2)在Xcode中:项目文件=>签名(调试)=>配置文件=>导入文件=>选择带1的文件

对于那些仍然在Xcode8中与这个问题作斗争的人。对于我来说，这是一个重复的证书问题，这是我解决它的方法:

我读了尼克的回答，然后开始了我的调查。我检查了我的特定案例中的所有密钥和证书(在~/Library/Keychains/System.keychain中)。

When I opened the file, I found that I had two iPhone Distribution Certificates (that was the certificate that Xcode was requesting me), one with the iOS Distribution private key that I have been using since the beginning, and another iPhone Distribution Certificate which its private Key had a name (iOS Distribution:NAME) that wasn´t familiar for me. I deleted this last certificate, started Xcode again and the problem was gone. xCode wasn´t able to resolve that conflict and that´s why it was giving signing certificate error all the time.

检查你的钥匙链，也许你有一个重复的证书。

我取消勾选，然后勾选“自动管理签名”选项。这为我解决了问题。

有很多方法可以解决这个问题，比如启用自动签名等。但是如果您想了解这个错误的原因，您需要查看错误消息。

它表示您在“常规”选项卡中选择的配置文件不包含您在“构建设置”中选择的签名证书->“代码签名标识”。

通常，如果在“生成设置”下为调试标识选择了分发证书->“代码签名标识”，则会发生这种情况。

如果这发生在“签名(调试)”下，也可能是“签名身份”->“iOS开发”不包括在配置配置文件中。

I haven't seen this mentioned yet but if you are still having issues after recreating your provisioning profiles, deleting the existing ones you have in your Provision Profiles folder, checking for dupes in your Keychain, etc (all other answers ITT), open your Target > Build Settings > Code Signing and make sure everything looks consistent in there. For example, I had changed the Code Signing Identify for Debug to a Distribution identity, which obviously wouldn't work as the Development Provisioning Profile doesn't have the Distribution certificate and was causing the error in the first place.

对于那些应该继续使用不自动的原因

打开keyChain访问，看看是否有两个相同的认证，如果有两个或更多，只需删除到一个，它将工作:)
