Sorry to interject (Sunday afternoon and all...)
Have you tried added an #error directive to Vision.mm (that proves
whether it is being compiled or not).
Then add the #error directive just before calling your C++ code. And
add the #error directive into your C++ code to see if it is getting
compiled.
#error WTF?
Back to Sunday afternoon...
