session.subscribe() is not working on XCode 11.3.1

Publish is working fine.
I am making the subscribe call once the connection happens, but there is no response to the subscribe call, no error or sucess

Yeah, the completion callback is never called, however my app is able to receive messages.

I've seen this issue too. It looks the the subscribe request is sent out with a message id of 1, but the response comes back with a message id of 0. This means the relevant callback won't be called. I wonder if it is a remote side issue as the message ids are wrong.

PR#45(#45) solve this issue.
i.e. relevant callback will be called.

I checked on Xcode11.6.
