值得注意的是，自动签名每次都失败了，直到我手动删除了本地配置文件: ~ /图书馆/ MobileDevice /配置概要文件

在这之后，自动签名工作得很好，它从苹果服务器上获得了正确的配置文件。

这只影响了一些构建，特别是那些我手动为手表应用程序创建配置文件的构建。

Delete the developer certificate that does not have a private key. Delete the provisioning profile from your machine using go to folder (~/Library/MobileDevice/Provisioning Profiles) Then first check then uncheck the Automatically manage signing option in the project settings with selecting team. Sing in Apple developer account and edit the provisioning profile selecting all available developer certificates then download and add to XCODE. Select the provisioning profile and code signing identity in project build settings

我收到了苹果公司的一封邮件:

Dear John Doe, The following certificate has either been revoked by a member of your development team or has expired: Certificate: iOS Development Team Name: Honey Team, LLC This does not affect apps that you've submitted to the App Store or your ability to update your apps. If you're using provisioning profiles that contain this certificate, they must be recreated before they can be reused. For details, see the "App signing overview" section of Xcode Help. Best regards, Apple Developer Program Support

我创建了一个新证书，撤销了之前的证书(在本地和任何其他开发人员的mac上)。为了让它工作，我必须下载新的配置文件。

解决方案是:

登录到苹果开发者帐户 删除/撤销以前以我的名字创建的证书。 将新的证书添加到供应配置文件中。您可以根据有效期来识别较新的 再次从Xcode下载。下载所有配置文件 重启Xcode

我个人没有这样的机会。这种访问权限只对我们团队的管理员开放，因此我没有截图，也不确定这些步骤是否100%正确。

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。

我为此挣扎了很多天。

步骤1: 删除所有证书，配置文件，appID，密钥等从开发帐户。

步骤2: 重新创建推送通知证书、配置文件、应用ID等。

步骤3: 从keychain中删除所有证书。

步骤4: 清除~/Library/MobileDevice/ provisioning Profiles中的所有配置文件。

步骤5: 只添加了所需的配置文件并进行了测试。它工作得很好。
