Coding .cpp to .dylib on mac

does anyone know how to add this file/script, to a .dylib on mac with xcode? I just need thirdperson whenever I do hvh's.
#include "Hooks.h"
#include "Globals.h"
#include "Cheats.h"

ThirdPersonFn oThirdPerson;

bool __fastcall Game::hkdShouldDrawLocalPlayer(void* ecx, void* edx, CBaseEntity* pPlayer)
{
if (Options.Visuals.ESP.ThirdPerson)
return true;

oThirdPerson(ecx, edx, pPlayer);

}
