# CocoaMQTT
MQTT v3.1.1 and v5.0 client library for iOS/macOS/tvOS written with Swift 5
## Build
Build with Xcode 11.1 / Swift 5.1
IOS Target: 12.0 or above
OSX Target: 10.13 or above
TVOS Target: 10.0 or above
## xcode 14.3 issue:
```ruby
File not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a
```
If you encounter the issue, Please update your project minimum depolyments to 11.0
## Installation
### CocoaPods
To integrate CocoaMQTT into your Xcode project using [CocoaPods](http://cocoapods.org), you need to modify you `Podfile` like the followings:
```ruby
use_frameworks!
target 'Example' do
pod 'CocoaMQTT'
end
```
Then, run the following command:
```bash
$ pod install
```
At last, import "CocoaMQTT" to your project:
```swift
import CocoaMQTT
```
### Carthage
Install using [Carthage](https://github.com/Carthage/Carthage) by adding the following lines to your Cartfile:
```
github "emqx/CocoaMQTT" "master"
```
Then, run the following command:
```bash
$ carthage update --platform iOS,macOS,tvOS --use-xcframeworks
```
At last:
On your application targets “General” settings tab, in the "Frameworks, Libraries, and Embedded content" section, drag and drop CocoaMQTT.xcframework, CocoaAsyncSocket.xcframework and Starscream.xcframework from the Carthage/Build folder on disk. Then select "Embed & Sign".
## Usage
Create a client to connect [MQTT broker](https://www.emqx.com/en/mqtt/public-mqtt5-broker):
```swift
///MQTT 5.0
let clientID = "CocoaMQTT-" + String(ProcessInfo().processIdentifier)
let mqtt5 = CocoaMQTT5(clientID: clientID, host: "broker.emqx.io", port: 1883)
let connectProperties = MqttConnectProperties()
connectProperties.topicAliasMaximum = 0
connectProperties.sessionExpiryInterval = 0
connectProperties.receiveMaximum = 100
connectProperties.maximumPacketSize = 500
mqtt5.connectProperties = connectProperties
mqtt5.username = "test"
mqtt5.password = "public"
mqtt5.willMessage = CocoaMQTTMessage(topic: "/will", string: "dieout")
mqtt5.keepAlive = 60
mqtt5.delegate = self
mqtt5.connect()
///MQTT 3.1.1
let clientID = "CocoaMQTT-" + String(ProcessInfo().processIdentifier)
let mqtt = CocoaMQTT(clientID: clientID, host: "broker.emqx.io", port: 1883)
mqtt.username = "test"
mqtt.password = "public"
mqtt.willMessage = CocoaMQTTMessage(topic: "/will", string: "dieout")
mqtt.keepAlive = 60
mqtt.delegate = self
mqtt.connect()
```
Now you can use closures instead of `CocoaMQTTDelegate`:
```swift
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:
```swift
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
```
Note: Please use openssl version 1.1 (e.g. `brew install [email protected]`), otherwise you may not be able to import the generated .p12 file to the system correctly.
## MQTT over Websocket
In the 1.3.0, The CocoaMQTT has supported to connect to MQTT Broker by Websocket.
If you integrated by **CocoaPods**, you need to modify you `Podfile` like the followings and execute `pod install` again:
```ruby
use_frameworks!
target 'Example' do
pod 'CocoaMQTT/WebSockets'
end
```
If you're using CocoaMQTT in a project with only a `.podspec` and no `Podfile`, e.g. in a module for React Native, add this line to your `.podspec`:
```ruby
Pod::Spec.new do |s|
...
s.dependency "Starscream"
end
```
Then, Create a MQTT instance over Websocket:
```swift
///MQTT 5.0
let websocket = CocoaMQTTWebSocket(uri: "/mqtt")
let mqtt5 = CocoaMQTT5(clientID: clientID, host: host, port: 8083, socket: websocket)
let connectProperties = MqttConnectProperties()
connectProperties.topicAliasMaximum = 0
// ...
mqtt5.connectProperties = connectProperties
// ...
_ = mqtt5.connect()
///MQTT 3.1.1
let websocket = CocoaMQTTWebSocket(uri: "/mqtt")
let mqtt = CocoaMQTT(clientID: clientID, host: host, port: 8083, socket: websocket)
// ...
_ = mqtt.connect()
```
If you want to add additional custom header to the connection, you can use the following:
```swift
let websocket = CocoaMQTTWebSocket(uri: "/mqtt")
websocket.headers = [
"x-api-key": "value"
]
websocket.enableSSL = true
let mqtt = CocoaMQTT(clientID: clientID, host: host, port: 8083, socket: websocket)
// ...
_ = mqtt.connect()
```
## Example App
You can follow the Example App to learn how to use it. But we need to make the Example App works fisrt:
```bash
$ cd Examples
$ pod install
```
Then, open the `Example.xcworkspace/` by Xcode and start it!
