Xcode beta 6 错误

Question

致在 Bata 6 中遇到类似问题的任何人。我通过删除 /Users/[您的用户名]/Library/Developer/Xcode/DerivedData 中的内容解决了这个问题，如本文Suddenly getting compiler crash "arrayForceCast" in Swift XCode beta 6中所示。

我刚刚安装了 Xcode beta 6，遇到了非常不寻常的错误。我无法弄清楚它们是什么。

Answer 1

是的！我也完全被这些错误弄糊涂了。

然后我记得删除项目的“DerivedData”（或者像我一样，删除整个文件夹），在这里找到：

~/Library/Developer/Xcode/DerivedData

（感谢@drmarvelous）

Answer 2

升级到 xcode 6 beta 6 后出现同样奇怪的错误。对我来说，问题已通过 Product -> Clean 解决。如果这不能解决错误按住选项键并再次单击菜单栏中的Product，那么您将在下拉菜单中看到Clean Build Folder... 点击它。

Answer 3

我遇到了同样的问题，但单独删除“DerivedData”文件夹对我不起作用。我不得不在位置的高级部分将构建位置更改为“唯一”。我相信这可能是因为我必须隔离 xcode 才能使用以下命令打开它：

sudo xattr -dr com.apple.quarantine /Applications/Xcode6-Beta6.app

但我不确定。
