QNClient

This section explains how to create and register a QNClient

First step needed is configure client with backend url

QNClient.configure(with: QNClient.Options(
                   serverUrl: "serverUrl",
                   xmppHost: "xmppHost",
                   xmppPort: "xmppPort"
                   ))

At this point we need Sessions class to authenticate an User, we can use token, basic or anonymous authenticate method, and as response receives a task with a Bool or ClientError

    QNClient.client.sessions.connect(authentication: .basic(username: "username", password: "password")) { result in
        switch result {
        case .success:
            print("Login successfully")
        case let .failure(error):
            print("Login failure: \(error)")
        }
    }

    QNClient.client.sessions.connect(authentication: .token(token: "aToken", provider: "aProvider")) { result in
        switch result {
        case .success:
            print("Login successfully")
        case let .failure(error):
            print("Login failure: \(error)")
        }
    }

To receive state changes in QNClient we need to set a delegate SessionDelegate

class SessionsStateDelegate: SessionDelegate {
    func qnClient(didChangeServerState serverState: ServerState, didChangeStackState stackState: StackState) {
        print("New state: \(serverState) \(stackState)")
    }
}
let delegate = SessionsStateDelegate()
QNClient.sessions.delegate = delegate

To close QNClient session send logout action with Auth class

QNClient.client.sessions.disconnect { _ in
        // Actions on disconnect
}

QNClient.configure creates a new client accesible from QNClient.client, but other clients still alive, so QNClient.client.sessions.disconnect is required to clean a Session
