Usage

Use closures to get notified of events


public var didRecieveMessage: ((_ mqtt: MQTTClient, _ message: MQTTMessage) -> Void)?
public var didRecieveConack: ((_ mqtt: MQTTClient, _ status: MQTTConnackResponse) -> Void)?
public var didSubscribe: ((_ mqtt: MQTTClient, _ topic: String) -> Void)?
public var didUnsubscribe: ((_ mqtt: MQTTClient, _ topic: String) -> Void)?
public var didConnect: ((_ mqtt: MQTTClient, _ connected: Bool) -> Void)?
public var didDisconnect: ((_ mqtt: MQTTClient, _ error: Error?) -> Void)?
public var didChangeState: ((_ mqtt: MQTTClient, _ state: MQTTConnectionState) -> Void)?

Connect to a MQTT Broker

import MQTTKit

let mqtt = MQTTClient(host: "localhost")

mqtt.didConnect = {mqtt, connected in
  // Gets called when a connack.accepted is recieved
}
// Or
mqtt.didRecieveConnack = {mqtt, response in
  // Gets callen when connack is recieved
}

mqtt.connect()

Subscribe and unsubscribe to topics

mqtt.didSubscribe = {mqtt, topic in
  // Gets called when suback is recieved
}

mqtt.didUnsubscribe  = {mqtt, topic in
  // Gets called when unsuback is recieved
}

mqtt.subscribe(to: "/my/topic")
mqtt.unsubscribe(from: "/my/topic")

Publish and recieved messages

let messagePayload = "Some interesting content".data(using: .utf8)!
mqtt.publish(to: "/my/topic", payload: messagePayload, qos: .QoS0, retained: false)

mqtt.didRecieveMessage = {mqtt, message in
  print(message)
}
