Delegate methods for typing indicator on Twilio chat not being called

Question

Working on a Swift chat application. On one device, I join a channel with unique name "private:chat", and then I call channel.typing() on the channel (as is mention in docs). On another device, I again create a client with a delegate set to self:

TwilioChatClient.chatClient(withToken: token, properties: nil, delegate: self) { (result, chatClient) in
    self.client = chatClient
}

And then I implemented typingStartedOn delegate method to listen to typing on the channel.

func chatClient(_ client: TwilioChatClient, typingStartedOn channel: TCHChannel, member: TCHMember) {
    print(">>>>>>>>>>>>> typing on \(channel.uniqueName) by \(member.identity)")
}

However, the delegate method does not get called, even though I confirmed that the channel.typing() gets called by the other account on the other device. The docs inline code in JS, but based on iOS chat demo app I came to conclusion that in Swift the delegate methods are the way to go.

Any idea what might be going on here?

EDIT: Some (haven't tested all) of the other delegate methods, such as synchronizationStatusUpdated, are getting called.

Can you share the code you are using to start the typing indicator for the channel? — philnash, Aug 22 '18 at 05:26

So after all, the issue was not in the iOS client, but in our implementation of the access token server.

As @rbeiter noted in his comment on GitHub issue, Twilio does not send typing indicator if the user identity is the same on both devices. I was setting the identity properly on both devices to keep it different, but our access token server ignored the identity parameter and used a hardcoded value. Thus from Twilio viewpoint, the same user was on both devices. Fixing the access token server fixed the problem.
