我也有同样的问题，我的应用程序在模拟器上工作正常，但在设备上崩溃了，因为我的午餐应用程序，并给出如上所述的错误。我已经尝试了所有的答案和解决方案。在我的情况下，我的项目我有多个目标，我从目标A创建了重复的目标B，目标B工作正常，而目标A崩溃了。我为每个目标使用不同的图像资产。在搜索和做谷歌之后，我发现了一些可能对某人有帮助的东西。

当我改变两个应用程序的启动图像资产的名称时，应用程序停止崩溃。例如，目标A启动映像资产名称LaunchImage A。目标B午餐映像资产名称LaunchImage B，并在每个目标的General Tab中正确分配。我的应用程序运行良好。

我在试图在一个私人pod上运行单元测试时遇到了这个问题。

每个人建议的我都做了。毫无效果。

我所要做的就是在不同的模拟器上运行单元测试。

我没有尝试重置模拟器的内容和设置，也许这也可以¯_()_/¯

换了新mac后，我也遇到了同样的问题，几个小时后，我尝试了问题中所有建议的答案，但没有一个对我有效。

我的解决方案是安装这个丢失的证书。 http://developer.apple.com/certificationauthority/AppleWWDRCA.cer

在这里找到了答案。 https://stackoverflow.com/a/14495100/976628

这些解决方案似乎都不起作用，但当我将全球开发人员证书的权限更改为使用系统默认值时，它就起作用了。我在下面的链接中包含了步骤和截图

我鼓励你在苹果漏洞报告中登录，因为苹果真的应该解决这个巨大的错误: https://stackoverflow.com/a/41401354/559760
