Framework build failed from Unity xcode project

Hello,
I asked Unity forum, but I post also here because xcode build error.

I build xcode project from Unity 2018.3.0f2.
And I create framework project from Xcode 11.5 version.
I import some files from Xcode project which built from Unity, to framework project.
I have build error, but I can't find solution from web search.

Error:
Unknown type name '_LIBCPP_INLINE_VISIBILITY' in stdlib.h

Code Block 
inline _LIBCPP_INLINE_VISIBILITY long      abs(     long __x) _NOEXCEPT {return  labs(__x);}

Unknown type name '_LIBCPP_CONSTEXPR' in limits c++

Code Block 
static _LIBCPP_CONSTEXPR const bool is_signed = false;

I follow some instruction for "How to embed a Unity game into an iOS native Swift App",
"Integrate Unity 5 in a native iOS app with Xcode 7". (this links are not posted)

I doubt build setting for c++ library, but I cannot solution for this build error.

I set Search Paths / Header Search Paths and Library Search Paths with Unity build xcode project. (Classes and Libraries folders)
Apple Clang - Language - C++ / C++ Language Dialect : GNU++11 and C++ Standard Library : libc++

Thank you.
