I should have been more specific. Sorry about that.

Yes, when including <Python/Python.h> in Xcode, incorporating the framework. In particular, I'm embedding 3.8 in an application (previously used the system Framework, which was 2.7, which worked but Apple has warned that it may disappear....).  

The Xcode error is:

In file included from /Users/gaige/MyApp/Code/PythonImporter.m:10:

#include "cpython/initconfig.h"
         ^~~~~~~~~~~~~~~~~~~~~~

python-framework is in the framework search path.

Let me know if there's something further I can clarify.
