The file “base.app” couldn’t be opened because you don’t have permission to view it.

Base项目是在Xcode7上创建的，升级Xcode8以后，编译时候提示错误：

The file “base.app” couldn’t be opened because you don’t have permission to view it.

应该是由于Build Settings->Build Options->Compiler for C/C++/Objective-C的LLVM版本变化导致。

解决办法：

1.找到Xcode项目文件目录Products，右键->在Finder中查看

2.删除项目文件目录Products下的xxx.app

3.此时xxx.app变为红色，重新编译运行即可

原标题：The file “base.app” couldn’t be opened because you don’t have permission to view it.
