Hello, I am testing PJSIP inside a Swift iOS app, just using PJSIP not PJSUA. After configuring, building and setting up the bridging header file, everything seems right. I can init PJLIB and PJLIB-UTIL successfully. But, I have encountered an issue that the *pjsip_endpoint* object cannot be found in scope. [image: image.png] Having a look at the implementation. I see the type definition is in sip_types.h but the actual struct is defined in *sip_endpoint.c* and not in *sip_endpoint.h*. Unlike other objects like pjsip_transaction, pjsip_event, etc; that have its struct definition in their header files. Can anyone elaborate on this implementation? And, if I'm using it in the wrong way, how can I declare a *pjsip_endpoint* object inside a Swift application? Any help would be much appreciated. Many thanks! Andrés --
