transition from asyncore to asyncio

Question

I am currently trying to transition from asyncore to asyncio since I am porting some old code from python 27 to python 35. But I am not very familiar yet with both.

Here is a condensed version of the problematic part:

import socket
import asyncore


mapDict = {}
fc = FeedbackController(port)
fc.start()

class FeedbackController(object):
     def __init__(self, port=None):       
                self.ipcchannel = IPCConnectionHandler(self, theMap=mapDict)
                self.udpconnectionhandler = UDPDispatcher(self, theMap=mapDict)


    def start(self):
                asyncore.loop(timeout=60.0,map=theMap)

    …

class UDPDispatcher(asyncore.dispatcher):
    def __init__(self, theMap):
        asyncore.dispatcher.__init__(self, map=theMap)
        self.create_socket(socket.AF_INET, socket.SOCK_DGRAM)
        self.bind((LOCALHOST, FC_PORT))

class IPCConnectionHandler(asyncore.dispatcher):
    def __init__(self,theMap=None):
        asyncore.dispatcher.__init__(self, map=theMap)
        self.create_socket(socket.AF_INET, socket.SOCK_STREAM)
        self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.bind((LOCALHOST, IPC_PORT))
        self.listen(5)

At the moment, I am running on Macos Sierra and it crashes when the asyncore.loop is called

Any help on how to transition would be great
