~/user.pch' file not found

解决方法:

选中工程名 —> Build Settings —> 搜索Language —> 找到Apple LLVM 7.0 - Language  —> 找到Prefix Header项 —>双击填写.pch文件的路径 —> 运行

2）报错：

error: PCH was compiled with module cache path '/Users/zmit/Desktop/WaterWave-master
/DerivedData/ModuleCache/OH9RS6URELRZ', but the path is currently '/Users/zmit/Desktop
