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.

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。

我也有同样的问题，原因是佩妮。在生成设置中选择了错误的配置文件和证书。我几天前才这么做过。所以，你不需要在xcode中启用“automatic”。在执行此操作之前，请检查构建设置中的配置文件。

我在最近将Xcode更新到9.3版本后遇到了这个问题 问题是在代码签名(在调试下)证书被设置为分发证书而不是开发证书，所以这阻止了我在我的设备上安装应用程序。

以下是我解决这个问题的方法。

项目->目标->选择你的应用程序->构建设置->代码签名身份->调试->双击“iPhone Distribution”并将其更改为“iPhone Developer”。

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。

您还可以使用Fastlane工具包解决代码签名问题。作者投入了大量精力来有效地自动化构建、签名iOS应用程序(等等)。

因此，在上述套件中，有一个工具sigh，它神奇地解决了任何签名问题，因此得名:)这里的好处是，这个工具封装了关于常见签名问题的知识，可以检测和解决大多数问题。

Fastlane安装为Ruby gem:

Gem安装fastlane

然后简单地引用:

快速的叹息——发展

回答两个问题，瞧:

[11:56:55]: No existing profiles found, that match the certificates you have installed locally! Creating a new provisioning profile for you
[11:57:01]: Creating new provisioning profile for 'com.myapp' with name 'com.myapp Development'
[11:57:06]: Downloading provisioning profile...
[11:57:09]: Successfully downloaded provisioning profile...
[11:57:09]: Installing provisioning profile...

最后，进入Build Settings -> Signing，切换到新创建的配置文件，其名称您刚刚在命令回显中看到。

此示例用于开发代码签名问题(在设备上运行)。查看所有其他选项的叹息文档。
