The current version of the socket io client library for IOS (socketio/socket.io-client-swift:15.x) does not yet support socket io server version 3.x.

Rationale: There was a problem with the default namespace declaration under the new protocol. If you enable debug mode, you will see that Socket server still receives message from client but events such as on connection, emit are not triggered.

Solution: Downgrade your NodeJS socket io server version to version 2.x
