Mixing C++

I know Xcode can mix C++ and Objective C code, but it supported by the ue4 and the build system? I.e. is it possible to write Objective C code only by calling C++ classes from it?

Yes, you can mix them. All .cpp files in UE4 are compiled as .mm by our build system. Just be aware that this will only work for Mac and iOS, as we currently do not support using ObjC on non-Apple platforms.

Hi,I could use objC but only when all code in one .mm file. How could I use them as usually in XCode? Many thanks.
