尝试直接从会员中心下载证书/配置文件，而不是从Xcode下载。

当我从会员中心手动下载它们时，它为我工作了。

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.

在我的情况下，在钥匙串我有两个证书同名，我删除了其中一个证书是重复的，然后它解决了这个问题。

为了解决这个问题，

我只是在项目设置通用选项卡上启用了“自动管理签名”，在启用之前，我担心它可能会有一些副作用，但一旦我启用，它就为我工作了。

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

我有我撤销的证书的剩余私钥，证书没有了，但私钥没有。删除它们就解决了问题。

要找到他们:

打开钥匙串访问 点击左侧菜单类别下的“键” 寻找未绑定证书的iOS Developer:…"密钥 我删除了它们，问题就解决了

图中高亮显示的密钥是一个没有证书的样例私钥。
