我不确定这是否能解决每个人的问题，但我遇到了完全相同的问题，它为我解决了这个问题.在钥匙串访问"中，我将以下证书的信任设置设置为使用系统默认值":

I'm not sure if this will fix it for everyone, but I had the exact same problem and it solved the problem for me. In Keychain Access, I set the trust settings to "Use System Defaults" for the following certificates:

• 苹果全球开发者关系认证中心
• 开发人员ID认证机构
• iPhone开发者:{email}
• iOS发行版

其中一些以前被设置为始终信任"，并且更改它似乎可以解决问题.但是，当运行Xcode时，它最初仍然无法正常工作，因此我清理了构建并重新启动了Xcode，最终启动了该应用程序.

Some of them were set to "Always Trust" before, and changing it seemed to resolve the issue. When running Xcode however, it initially still did not work, so I cleaned the build and restarted Xcode, and the application finally launched.
