Bridging objective-c library in swift project does not work

In my swift project in need to use snmp++ project ( http://ift.tt/1fyN2Ff ). The snmp++ project is written in c++ and then objective-c wrapper is created for functions.

The project generates libMobileSNMP_PP.a file which i include in my swift project and then create a bridging header and in the bridging header inport "XISMobile_SNMP_PP.h".

Also included .mm and .h files in the swift project as shown in the attached image example1

at compile it gives "could not reference bridging file in the app".

I refered link Can I mix Swift with C++? Like the Objective - C .mm files but still issue exist.

I even tried steps as given in example as shown http://ift.tt/1P42pSz but no success.

Please tell where i'm doing or missing any step.
