我也有同样的问题，但是，这是由于我在我的Mac上设置了“FileVault”。我进入我的钥匙链，将“login”设置为默认值，这就解决了它。

以下是我所做的。

Make sure your certificates have not expired, make sure you delete all the expired ones. Get new ones etc, Once you have make sure all that is the way it should be, then focus on your project files. in finder , go to your .xcodeproj files then show package contentes. open project.pbxproj in xcode or textedit. find every refrense to PROVISIONING_PROFILE and remove the GUID, just leave empty "" Depending on your project you should have about 12+ refrences, remove all of the GUIDS. Save file, then reopen your project in XCODE Re select the correct provision profiles for all possible code signings( they should not all be the same) Build your project and you should be good to go.

我认为Xcode在某种程度上混淆了，从项目中删除了所有的Provision Profiles。Pbxproj，然后重新选择一个有效的配置文件将使它直。

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。

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.

我也有同样的问题，但是，这是由于我在我的Mac上设置了“FileVault”。我进入我的钥匙链，将“login”设置为默认值，这就解决了它。

以下是简单的步骤:

从计算机上的keychain(其中已经包含开发密钥)开始，创建一个证书请求。将请求上传到开发站点并创建证书。 使用证书创建配置文件。 下载配置文件并将其放到Xcode上。

现在所有的点都连接起来了，应该可以工作了。这对开发和推广都适用。
