The file "base. app" couldn't be opened because you don't have permission to view it., base. apppermission

The Base project is created on Xcode7. After Xcode8 is upgraded, an error is prompted during compilation:

The file"Base. app"Couldn'T be opened because you don'T have permission to view it.

It should be caused by the LLVM version change of Build Settings-> Build Options-> Compiler for C/C ++/Objective-C.

 

Solution:

1. Find the Xcode project directory Products, right-click it, and choose Finder to view it.

2. Delete xxx. app under Products in the project file directory.

3. At this time, the xxx. app turns red and you can re-compile and run it.
