此问题是由于您的配置文件中的证书中的私钥与您的密钥链中的私钥不匹配。我解决这个问题的方法是

delete all iPhone Developer certificate in keychain. delete all certificate in apple account. using xcode "Manage Certificates" to add certificate, sometime you still have certificate in your Mac, but I do not know where it is for now, and if added successfully, your apple account will display that certificate too, and then you can create your profile with that certificate and download ... goto 5 if you use "Manage Certificates" can't add certificate, you can create a new certificate, and do remain steps. finish.

Xcode版本8的代码签名问题也是如此。

“启用自动签名”，然后从下拉菜单中选择一个团队，帮助我解决了这个问题。

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。

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。

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

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。
