ios - Messenger cannot connect to a XMPP server from the first attempt -

i wrote 2 functions:

if let stream = xmppstream {         if stream.isauthenticated(){             println("logged in")         } else {             println("something wrong")         } }   func xmppstreamdidconnect(sender: xmppstream) {     println("xmppstreamdidconnect")     isopen = true     var error: nserror?     if (xmppstream!.authenticatewithpassword(password.text, error: &error) ) {         println("authentification successful")         performseguewithidentifier("gotobuddylist", sender: nil)     } } 

and when run app prints in terminal:

something wrong xmppstreamdidconnect authentification successful 

even if putted true credentials prints @ first [something wrong] , later [authentification successful]. why happens?

i want alert users in case of [something wrong], not in [successful] case, alert in successful case, too.

implement xmppstreamdidauthenticate , didnotauthenticate methods of xmppstreamdelegate .

after calling authenticatewithpassword client authentication surely end in above 2 function (xmppstreamdidauthenticate , didnotauthenticate) until stream.isauthenticated() return “0”.
