这事让我非常担心。我刚刚下载了iPhone 3.0 SDK，但现在我无法让我的配置文件工作。以下是我的尝试:
删除所有配置配置文件 删除登录keychain 创建新的“登录”钥匙链，使它 默认的 创建一个新的证书签名请求 创建新的开发人员和分销渠道 证书在苹果开发者中心 下载并安装它们 下载并安装WWDR证书 创建一个新的配置文件和 双击它来安装
所有的证书报告都是有效的，但是Xcode仍然不能识别它们。接下来我该试试什么?
编辑:
我完全重新安装了Mac OS X，从一个新的安装安装了3.0 SDK，仍然有同样的问题。
当前回答
我也遇到了同样的问题，试过了所有方法。不管出于什么原因，解决方案是我所有的证书都迁移到一个名为“microsoft_intermediate_certificates”的密钥链上。因为它可能发生在Xcode升级期间，我完全不知道为什么，但它可能会帮助到一些人。
我将微软钥匙串的所有内容移动到登录钥匙串，一切恢复正常。
其他回答
我发现我需要拖动distribution_identity。我从开发人员程序门户网站上的“Certificates -> Distribution”页面下载的cer文件到密钥链访问程序中，然后这个错误就消失了。
我也遇到过同样的问题。这是因为证书的私钥在您的机器上不存在。
If you are now using a new machine and download the certificate from website: You can export the certificate from the old machine and then import on the new machine. If you share the developer account with someone: You ask the account owner to send you an invitation and become a team member of that account. Then you can create your own certificate from scratch. If you don't want to handle all these sh*t: Just revoke the certificate on website and delete the copy on your local machine. Then request a new one. This should be the ultimate way for solving such issue.
我登录了开发人员帐户并撤销了开发证书。撤销和下载开发证书后，我双击新下载的证书，这一次私钥在开发证书下的KeyChain访问。
你试过重启你的Mac和设备吗?蹩脚的回答，但我总是先试一下。
For Xcode 13 (maybe earlier?) - The key to this is to use the "Build Settings" tab, not the "Signing and Capabilities" tab in your Target Settings. Once you are in "Build Settings", search for the "Signing" section (you can type "Signing" in the search box). There you will see a sub-section called Code Signing Identity. In that section you can click on each line and directly choose any certificate you have in your keychain. You need to do that for all of the relevant configurations (the ones that you want to upload to TestFlight/AppStore). When you go back to the "Signing and Capabilities" tab, you should see the results of what you did and the error should have gone away.
我从下面的答案中得到了灵感:https://stackoverflow.com/a/37043501/826946
但我认为明确地列出这一点可能会有所帮助。
