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。

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

点击然后取消“启用自动签名”对我来说是有效的，尽管它所做的实际改变是:

Always_embed_swift_standard_libraries = yes;

或者在Xcode中，它被称为始终嵌入Swift标准库

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。

如果您尝试将应用程序上传到iTunes Connect(您的供应配置文件设置为分发)，请转到项目设置->构建设置->代码签名。请确保将所有调试和发布选项设置为您的分发配置文件。

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.
