I just downloaded the final version of xcode 6 and to compile a project that I was working with the beta, now generates the following error simulator apparently, someone can help me with this.

fatal error: file '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/

precompiled header '/Users/Lycros/Library/Developer/Xcode/DerivedData/ModuleCache/NZL05J5PKZ6B/
UIKit-301UUGFC4BK8R.pcm' was built

当我尝试在模拟器iphone 5s，6,6 plus以及两个可调整大小时编译时发生错误。
的工作方式不是iphone 5,4等。 。

推荐答案

退出Xcode并删除位于此处的模块缓存中的所有内容：

Quit Xcode and remove everything in the module cache located here:

〜/ Library / Developer / Xcode / DerivedData / ModuleCache

使用之前构建的缓存Xcode版本对于此版本的Xcode和SDK无效，这会导致您的错误。

The cache that was built with a previous version of Xcode is invalid for this version of Xcode and SDK, and that is causing your error.
