RabbitMQ Objective-C and Swift client

A RabbitMQ client, largely influenced by Bunny.

Test-driven from Swift and implemented in Objective-C, to avoid burdening Objective-C developers with Swift baggage.

Currently implemented

• 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
• OSX support
• PKCS12 client certificates using the TLS auth mechanism plugin
• PKCS12 client certificates using chained CAs
• Publisher confirmations
• Publish and consume messages as data
• Connection closure when broker doesn't send heartbeats fast enough
• Customisable consumer hooks
• basic.return support
• Transaction support

Installation with Carthage

1. Create a Cartfile with the following line:

   github "rabbitmq/rabbitmq-objc-client" ~> 0.9
   

   Run carthage, for example in a new project:

   carthage bootstrap --platform iOS
   

2. In your Xcode project, in the Build Phases section of your target, open up Link Binary With Libraries. Now drag Carthage/Build/iOS/RMQClient.framework into this list.

3. If you don't already have one, click the '+' icon under Build Phases to add a Copy Files phase.

4. Under Destination, choose Frameworks.

5. 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', '~> 0.9'
   

   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>.

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: \(m.body)")
   }
   q.publish("foo".dataUsingEncoding(NSUTF8StringEncoding)!)

5. Close the connection when done:

   conn.close()
   

See the tutorials for more detailed instructions.

Running Tests

First make sure you have xctool installed:

brew install xctool

Then start a local RabbitMQ node (any way you please, doesn't have to be from Homebrew or source), configure it using files under .travis/etc/, for example:

brew install rabbitmq
cp .travis/etc/* /usr/local/etc/rabbitmq/
/usr/local/sbin/rabbitmq-plugins enable --offline rabbitmq_auth_mechanism_ssl
brew services start rabbitmq

Then run a few setup steps:

bin/bootstrap-if-needed
/usr/local/sbin/rabbitmqctl add_user "O=client,CN=guest" bunnies
/usr/local/sbin/rabbitmqctl -p / set_permissions "O=client,CN=guest" ".*" ".*" ".*"

Finally, run the test suite:

xctool -project RMQClient.xcodeproj -sdk iphonesimulator -scheme RMQClient test
