Xcode在发布时崩溃

我正在开发一个iOS应用程序,我在应用程序中没有任何改变.但是在重新启动我的Mac时,Xcode每次都会崩溃.

不知道这是否重要,但我的聚光灯找不到任何应用程序,当我打开取景器并使用快捷键cmd + shift + HI时,看到一个白色的窗口.

Xcode不再启动并抛出此错误:

由于权限冲突,这可能是一个问题吗？

回答:

我将权限从我的OSX-Drive更改为每个人都可以写入和读取.一切正常.但我知道这是一个临时解决方案,所以我决定重新安装我的MAC,一切都很好.

~/Library/Developer/Xcode/DerivedData在终端中运行此命令删除:

rm -r ~/Library/Developer/XCode/DerivedData

如果这不起作用,在这一点和给定的信息,我可以建议删除并重新安装Xcode.
