send a binary json message to a udp server in swift

To send a binary JSON message to a UDP server in Swift, you'll need to follow these steps:

Encode your message as JSON.
Convert the JSON data into binary data.
Create a UDP socket and specify the host and port of the server.
Send the binary data over the UDP socket.

Here's an example implementation:


main.swift
import Foundation
import Socket // Install via CocoaPods or Swift Package Manager

let json = "{\"name\": \"John Doe\", \"age\": 29}" // Your JSON message to send
let jsonData = json.data(using: .utf8)! // Convert JSON to data

// Create a UDP socket and specify the server's host and port
guard let udpSocket = try? Socket.create(family: .inet, type: .datagram, proto: .udp) else {
    fatalError("Could not create UDP socket")
}
let serverAddress = Socket.createAddress(for: "localhost", on: 8080)
try udpSocket.setReadTimeout(value: 5)

// Send the binary data over the UDP socket
do {
    try udpSocket.write(from: jsonData, to: serverAddress)
    print("Binary JSON message sent successfully")
} catch {
    print("Error sending binary JSON message: \(error.localizedDescription)")
}

udpSocket.close() // Close the socket when done

This code uses the Socket library to create a UDP socket and send the binary JSON message to the specified server. If the message is sent successfully, it will print a success message. If an error occurs, it will print an error message.

Note that in this implementation, the server is specified as localhost on port 8080. You'll need to change these values to match your server's host and port.
