xmppStreamDidConnect not get called

[ghost]

Hey, gone thrw whole project , my problem is, I'm creating the framework in swift using Robbinson XMPP framework, I managed to set up the project, the delegate method bellow is getting called:

func xmppStreamWillConnect(_ sender: XMPPStream!) {
        print("will");
    }

but the delegate method below never gets called:

 func xmppStreamDidConnect(_ sender: XMPPStream!) {
        print("connect");
    }

i tried to put breakpoint in objc code, its hitting the // Notify delegates method (please ref screen shot ) but in my code its not get called ..Thanks
