Framework to send UDP broadcast messages and listen to responses using a Dispatch dispatch source.

iOS 9.3+, Swift 4.0

An example app is included demonstrating UDPBroadcastConnection's functionality. The example probably won't work for you out of the box since you need someone to listen and respond on the correct UDP port on your network.

Create a UDPBroadcastConnection on port 35602 with a closure that handles the response:

broadcastConnection = UDPBroadcastConnection(port: 35602) { [unowned self] (response: (ipAddress: String, port: Int, response: [UInt8])) -> Void in
    print("Received from \(response.ipAddress):\(response.port):\n\n\(response.response)")
}

Note: Make sure to keep a strong reference to broadcastConnection (e.g. by storing it in a property).

Add the following line to your Cartfile.

github "gunterhager/UDPBroadcastConnection"

Then run carthage update.

Just drag and drop the .swift files in the UDPBroadcastConnection folder into your project.

UDPBroadcastConnection is available under the MIT license. See the LICENSE file for details.
