如果你使用的是Xcode 11，确保你在“目标设置-常规”下的“框架”、“库”和“嵌入内容”中添加了框架。将嵌入状态从-“不嵌入”更改为“嵌入&签名”

唯一对我有用的是:

目标>构建阶段> [CP]嵌入Pods框架 取消勾选“在生成日志中显示环境变量”和“仅在安装时运行脚本”

None of these issues solved this for me. The problem in the end was pretty easy. It looks like its a pretty major Xcode bug which I have logged the problem and fix under Apple bug: 29820370. If you are struggling (as it seems like there are several pages of problems similar to this ) then it would be great if you can raise a bug on bug reporter: https://bugreport.apple.com/ and reference the bug I raised to gain visibility. I want to make Xcode back into the pleasure that it was before - and this is something I am sure Xcode should have fixed itself.

下面是解决方案: 1. 打开钥匙串-去苹果全球开发者证书。 2. 双击它 3.将权限级别从“始终信任”更改为使用“系统默认” 4. 保存并关闭 5. 重新启动Xcode，清理并构建项目，它应该消失了。

下面是正确设置的截图: 希望这能有所帮助!

I found that this issue was related only to the code signing and certificates not the code itself. To verify this, create the basic single view app and try to run it without any changes to your device. If you see the same error type this shows your code is fine. Like me you will find that your certificates are invalid. Download all again and fix any expired ones. Then when you get the basic app to not report the error try your app again after exiting Xcode and perhaps restarting your mac for good measure. That finally put this nightmare to an end. Most likely this has nothing to do with your code especially if you get Build Successful message when you try to run it. FYI
