RabbitMQ Objective-C and Swift client

A RabbitMQ client, largely influenced by Bunny.

Test-driven from Swift and implemented in Objective-C.

Supported iOS and macOS Versions

This library currently targets iOS 12+ and macOS 10.12+.

Dependencies

This library depends on

• CocoaAsyncSocket
• JKVValue

Installation with Carthage

1. Create a Cartfile with the following line:

github "rabbitmq/rabbitmq-objc-client" "v0.12.0"

Run Carthage, for example in a new project:

carthage bootstrap

1. In your Xcode project, in the Build Phases section of your target, open up Link Binary With Libraries. Now drag e.g. Carthage/Build/iOS/RMQClient.framework (choose Mac for OSX) into this list.
2. If you don't already have one, click the '+' icon under Build Phases to add a Copy Files phase.
3. Under Destination, choose Frameworks.
4. Click the '+' and add RMQClient.framework. Ensure Code Sign On Copy is checked.

Installation with CocoaPods

1. Add the following to your Podfile:

   pod 'RMQClient', '~> 0.12.0'
   

   We recommend adding use_frameworks! to enable modular imports (Objective-C only).

2. Run pod install.

3. Open your project with open MyProject.xcworkspace.

Objective-C users: importing with @import RMQClient; currently produces an error in Xcode (Could not build module 'RMQClient'), but this should not prevent code from compiling and running. Using crocodile imports avoids this Xcode bug: #import <RMQClient/RMQClient.h>.

Supported Features

• Publish and consume messages as strings
• Manipulate queues, exchanges, bindings and consumers.
• Asynchronous API using GCD queues under the hood (a delegate receives errors on a configurable GCD queue).
• Configurable recovery from network interruption and connection-level exceptions
• TLS support
• Client heartbeats
• Carthage support
• CocoaPods support
• iOS support
• MacOS support
• PKCS12 client certificates on iOS using the TLS auth mechanism plugin
• PKCS12 support for MacOS
• PKCS12 client certificates on iOS using chained CAs
• Publisher confirmations
• Publish and consume messages as data
• Customisable consumer hooks
• Connection closure when broker doesn't send heartbeats on schedule
• basic.return support
• Acknowledgement transaction support

Documentation

• Several RabbitMQ tutorials are provided for this client library.

(Basic) Usage Example

1. Instantiate an RMQConnection:

   let delegate = RMQConnectionDelegateLogger() // implement RMQConnectionDelegate yourself to react to errors
   let conn = RMQConnection(uri: "amqp://guest:guest@localhost:5672", delegate: delegate)

2. Connect:

   conn.start()

3. Create a channel:

   let ch = conn.createChannel()

4. Use the channel:

   let q = ch.queue("myqueue")
   q.subscribe({ m in
      print("Received: \(String(data: m.body, encoding: String.Encoding.utf8))")
   })
   q.publish("foo".data(using: String.Encoding.utf8))

5. Close the connection when done:

   conn.close()
