Xcode beta 6错误

Question

对于在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中所见< / p>

我刚刚安装了Xcode beta 6并且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搞糊涂了。

然后我记得删除＆＃34; DerivedData＆＃34;对于项目（或者像我一样，整个文件夹），可以在这里找到：

〜/库/开发商/ Xcode中/ DerivedData

（感谢@drmarvelous）

Answer 2

升级到xcode 6 beta 6后出现了同样的奇怪错误。对我来说，问题已通过Product -> Clean修复。如果这不能解决错误，请按住选项键并再次点击菜单栏中的Product，然后您会在下拉菜单中看到Clean Build Folder...点击它。

Answer 3

我遇到了同样的问题，但仅删除“DerivedData”文件夹并不适用于我。我必须在位置的高级部分中将构建位置更改为“唯一”。我相信这可能是因为我必须使用以下命令隔离xcode以使其打开：

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

但我不确定。
