Publish Message

To publish message to the broker, first make sure you have provided a MessageAdapter that is able to encode your object to the binary data format. For example, if you have a data struct that you want to send as JSON. Make sure, it conforms to Encodable protocol and pass JSONMessageAdapter in MQTTClientConfig when creating the CourierClient instance.

You simply need to invoke CourierSession/publishMessage(_:topic:qos:) passing the topic string and QoS enum. This is a throwing function which can throw in case it fails to encode to data.

let message = Message(
    id: UUID().uuidString,
    name: message,
    timestamp: Date()
)
        
try? courierService?.publishMessage(
    message,
    topic: "chat/1234",
    qos: QoS.zero
)
