I'm trying to include some C++11 headers in an iOS project, but XCode / Clang can't find them. I'm trying to include
Lexical or Preprocessor Issue 'memory' file not found
Lexical or Preprocessor Issue 'functional' file not found
C++ Language Dialect = C++11 [-std=c++11]
C++ Standard Library = libc++ (LLVM C++ standard library with C++11 support)
It turned out that Clang's error message was unhelpful: the root include for these files was a
.m file, compiling as Objective-C, so I renamed it to
.mm, to compile as Objective-C++, and it started working.
