iOS Swift XMLRPC Library

I need a light weight Swift XMLRPC library which can response data without async or background thread. Currently I'm using AlarmoFireXMLRPC which is almost perfect, only problem is it only comes with completeHandler or background thread included which is not useful in my use case. I want to execute sequential request. This is perfect example of what I need (without Asynchronous Calls) : [login to view URL] which is written in java. Also I need good serialisation at the end of response.
