Are you really sure is included only from a .cpp file?

I just tested on a fresh project, by adding a .cpp file and including , and it works, just as expected (same Xcode version, same SDK version).

But if I include in a .m file, then of course I got a «file not found» compiler error.

So double-check this, as the error may come from here.

Do you include from a .cpp file only, or from a .h file, intended to be used by a .cpp implementation?
Then maybe it's also included by a .m file, hence the error.

Also check your precompiled headers, if any, to see if you include some C++ stuff there...

Also remember, in that later case, that you can rely on the __cplusplus macro, when needed.
