Force Header Files to Compile as C++ in Xcode

I have an Xcode project for iOS in Xcode 7.0 that contains Objective-C, C++, and C code. Xcode tries to compile the C++ header files with the extension .h (not .hpp) as C header files which generates errors.

How do I fix this? There should be a setting for which files should be compiled as which language.

Individually header files doesn't compiled. Compiled source files where they included. If you include them in .c they will be compiled like C, if in .m - like Objective-c, if in .cpp - like C++, if in .mm - like Objective-C++.

It doesn't matter how you name them .h or .hpp.

If you have some portion of C++ code in h-file- you should put it in 

#ifdef __cplusplus
#endif

If you have some portion of Objective-C code in h-file you should put it in

#ifdef __OBJC__
#endif

This will make code inside this statement invisible for other languages.

You can find this statement in Xcode's generated pch-file.
