swift - iOS: "Include of non-modular header" with libxml -

i'm trying build own framework 'vbl' uses touchxml based on libxml.dylib

the framework building fine, whenever i'm trying use in project, got following error:

"include of non-modular header inside framework module vbl.cxmlnode" 

and that's because in header cxmlnode.h inside framework, have include libxml follows:

#include <libxml/tree.h> 

is safe set following property inside build settings yes?

allow non-modular included in framework modules 

but not work swift anyways, other suggestions?

you can try hide #include <libxml/tree.h> in private header or in .m file if can.

you can try create module.modulemap file libxml root header inside fool swift compiler:

module libxml [system] {     header "/applications/xcode.app/contents/developer/platforms/iphoneos.platform/developer/sdks/iphoneos.sdk/usr/include/libxml2/libxml/tree.h"     export * } 

then place file inside folder, -module/module.modulemap- example.

once did should link in import paths within swift compiler search path section of target build setting, , target's header search path :

$(srcroot)/module 

then in code, can use @import libxml;
