Opening import file for module 'Swift': Not a directory

Question

After following the instructions here to setup libxml on Swift: libxml/tree.h no such file or directory

I encountered an error while compiling which said:

Opening import file for module 'Swift': Not a directory

I've searched online and they recommending cleaning the project which didn't work for me. Any idea what's causing this error?

Answer 1

I got this error when I had an invalid path to a framework in my Framework Search Path and User Header Search Paths. I simply fixed the path by adding ".framework" to the end of the path, to make the path valid, and this error went away.

Answer 2

Issue cropped up after adding my first swift class to the project.

I fixed it by going into the build settings for ALL targets (including the actual project) and remove any erroneous paths from Framework Search Path.

Specifically:

1. Simplified the main target to:

   $(inherited)

   $(SRCROOT)

2. And by removing an old, erroneous path to libxml2 on the project.
