苹果LLVM编译器错误4.1
所以，我碰巧移动了一些文件夹，突然之间，我的项目发现，只是喜欢，而不是工作会很酷。 有人可以告诉我如何解决这个错误？ （编译irl的iPhone时出错。）
短错误：

和一个截图 
您需要编辑您的目标的构build设置，并更新“前缀头”来修复其path。
我有这个错误：缺lessMyProject-Prefix.pch，也缺lessCordovaLib_Prefix.pch，果然，我可以validation他们不是他们应该在哪里。
这是我想到的：
- 我把我的项目的所有文件从一个目录复制到另一个（事实）
- Finder以其智慧决定不复制以.p.pch结尾的文件
有道理的理由是，为了解决这个问题，我只需要将文件从原始位置复制到应该在的目录中。
