I am getting lexical or preprocessor issue i.e file not found after xcode 6.1 update. i have followed below stack overflow solution but no luck.
#import
in SearchPaths in both Project as well as in target
set HeaderSearchPath and LibrarySearchPaths to /usr/include/libxml2
this thing solve my issue may it will also help you
also set OTHER_LDFLAGS to -lxml2 to avoid any linker issues afterwards
