ZeroMQ for Swift 2 (Linux ready)

SwiftZMQ

SwiftZMQ is a ZeroMQ binding for Swift 2.

Features

• No Foundation dependency (Linux ready)
• Context
• Socket
• Message
• Poller
• Proxy

##Example

import SwiftZMQ

do {
    let context = try Context()

    let inbound = try context.socket(.Pull)
    try inbound.bind("tcp://127.0.0.1:5555")

    let outbound = try context.socket(.Push)
    try outbound.connect("tcp://127.0.0.1:5555")

    try outbound.sendString("Hello World!")
    try outbound.sendString("Bye!")

    while let data = try inbound.receiveString() where data != "Bye!" {
        print(data) // "Hello World!"
    }
} catch {
    // Something bad happened :(
}

Dependency

SwiftZMQ requires ZeroMQ version 4.2 to be installed. The easiest way on Mac OS X is through brew.

> brew install zeromq --with-libsodium --HEAD

Installation

Carthage

Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate SwiftZMQ into your Xcode project using Carthage, specify it in your Cartfile:

github "Zewo/SwiftZMQ"

Manually

If you prefer not to use a dependency manager, you can integrate SwiftZMQ into your project manually.

Embedded Framework

• Open up Terminal, cd into your top-level project directory, and run the following command "if" your project is not initialized as a git repository:

$ git init

• Add SwiftZMQ as a git submodule by running the following command:

$ git submodule add https://github.com/Zewo/SwiftZMQ.git

• Open the new SwiftZMQ folder, and drag the SwiftZMQ.xcodeproj into the Project Navigator of your application's Xcode project.

  It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter.

• Select the SwiftZMQ.xcodeproj in the Project Navigator and verify the deployment target matches that of your application target.

• Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.

• In the tab bar at the top of that window, open the "General" panel.

• Click on the + button under the "Embedded Binaries" section.

• You will see two different SwiftZMQ.xcodeproj folders each with two different versions of the SwiftZMQ.framework nested inside a Products folder.

  It does not matter which Products folder you choose from, but it does matter whether you choose the top or bottom SwiftZMQ.framework.

• Select the top SwiftZMQ.framework for OS X and the bottom one for iOS.

  You can verify which one you selected by inspecting the build log for your project. The build target for SwiftZMQ will be listed as either SwiftZMQ iOS or SwiftZMQ OSX.

• And that's it!

The SwiftZMQ.framework is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.
