I found solution, but it's not a best way. After reinstall XCode this issue was fixed.

我找到了解决方案，但这不是最好的方法。重新安装 XCode 后，此问题已修复。

回答by Pintouch

Did you try removing your project folder in the DerivedData folder before reinstalling xCode?

在重新安装 xCode 之前，您是否尝试删除 DerivedData 文件夹中的项目文件夹？

I had the same problem updating from beta 6 to beta 7, and that solved the problem.

我从 beta 6 更新到 beta 7 时遇到了同样的问题，这解决了问题。

回答by tuoxie007

I had the same problem, then I use git checkout old versions to find which commit cause the problem, and try to find the key problem code. My key problem code is something like this

我也遇到了同样的问题，然后我使用git checkout old versions查找导致问题的提交，并尝试找到关键问题代码。我的关键问题代码是这样的

func afunc() {
    class AClass() {
    }
    let ac = AClass()
    //....
}

Other code could make the same problem, occur in Swift Optimization, and swift compiler doesn't tell you the exact location. This must be a bug by Apple.

其他代码可能会出现同样的问题，发生在 Swift 优化中，并且 Swift 编译器不会告诉您确切的位置。这应该是苹果的bug。
