MQTT for iOS and macOS written with Swift

CocoaMQTT

MQTT v3.1.1 client library for iOS/macOS/tvOS written with Swift 5

Build

Build with Xcode 10.2 / Swift 5

Installation

CocoaPods

Install using CocoaPods by adding this line to your Podfile:

use_frameworks! # Add this if you are targeting iOS 8+ or using Swift
pod 'CocoaMQTT'  

Then, run the following command:

$ pod install

Carthage

Install using Carthage by adding the following lines to your Cartfile:

github "emqx/CocoaMQTT" "master"

Then, run the following command:

$ carthage update --platform iOS,macOS,tvOS

Last if you're building for OS X:

• On your application targets “General” settings tab, in the "Embedded Binaries" section, drag and drop CocoaMQTT.framework from the Carthage/Build/Mac folder on disk.

If you're building for iOS, tvOS:

• On your application targets “General” settings tab, in the "Linked Frameworks and Libraries" section, drag and drop each framework you want to use from the Carthage/Build folder on disk.

• On your application targets "Build Phases" settings tab, click the "+" icon and choose "New Run Script Phase". Create a Run Script with the following contents:

  /usr/local/bin/carthage copy-frameworks
  

• and add the paths to the frameworks you want to use under "Input Files", e.g.:

  $(SRCROOT)/Carthage/Build/iOS/CocoaMQTT.framework
  

Usage

Create a client to connect MQTT Broker:

let clientID = "CocoaMQTT-" + String(NSProcessInfo().processIdentifier)
let mqtt = CocoaMQTT(clientID: clientID, host: "localhost", port: 1883)
mqtt.username = "test"
mqtt.password = "public"
mqtt.willMessage = CocoaMQTTWill(topic: "/will", message: "dieout")
mqtt.keepAlive = 60
mqtt.delegate = self
mqtt.connect()

Now you can use closures instead of CocoaMQTTDelegate:

mqtt.didReceiveMessage = { mqtt, message, id in
	print("Message received in topic \(message.topic) with payload \(message.string!)")           
}

SSL Secure

One-way certification

No certificate is required locally. If you want to trust all untrust CA certificates, you can do this:

mqtt.allowUntrustCACertificate = true

Two-way certification

Need a .p12 file which is generated by a public key file and a private key file. You can generate the p12 file in the terminal:

openssl pkcs12 -export -clcerts -in client-cert.pem -inkey client-key.pem -out client.p12

Example App

You can follow the Example App to learn how to use it. But we need to make the Example App works fisrt:

$ cd Examples

$ pod install

Then, open the Example.xcworkspace/ by Xcode and start it!
