如何在iOS swift中使用UDP套接字传输音频？

我对这个网络概念真的很陌生，但我必须使用UDP套接字流式传输音频文件，在搜索了一周之后，我没有得到任何有用的东西。我使用了CocoaAsyncSocket，并尝试从发送方应用程序向接收方应用程序发送字符串，但它没有收到任何内容

import Foundation
import CocoaAsyncSocket

class OutSocket : NSObject, GCDAsyncUdpSocketDelegate {

var hostIP : String = "255.255.255.255"
var port : UInt16 = 50008
var socket : GCDAsyncUdpSocket!

override init() {
    super.init()

    setUpConnection()
}

func setUpConnection() {
    socket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main)
    do {
        try socket.connect(toHost: hostIP, onPort: port)
    } catch let err{
        print("Error Connecting, ", err)
    }
}

func sendData(message : String) {
    guard let data = message.data(using: .utf8) else { return }
    let str = String(data: data, encoding: .utf8)
    print(str!)
    socket.send(data, withTimeout: 1000, tag: 0)
}

func udpSocket(_ sock: GCDAsyncUdpSocket, didConnectToAddress address: Data) {
    print("didConnectToAddress")
}

func udpSocket(_ sock: GCDAsyncUdpSocket, didNotConnect error: Error?) {
    print("didNotConnect \(String(describing: error))")
}

func udpSocket(_ sock: GCDAsyncUdpSocket, didSendDataWithTag tag: Int) {
    print("didSendDataWithTag")
}

func udpSocket(_ sock: GCDAsyncUdpSocket, didNotSendDataWithTag tag: Int, dueToError error: Error?) {
    print("didNotSendDataWithTag")
    print(error!)
}
}
import Foundation
import CocoaAsyncSocket
class InSocket: NSObject, GCDAsyncUdpSocketDelegate {

var hostIP : String = "255.255.255.255"
var port : UInt16 = 50008
var socket : GCDAsyncUdpSocket!

override init() {
    super.init()

    setUpConnection()
}

func setUpConnection() {
    socket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main)

    do {
        try socket.connect(toHost: hostIP, onPort: port)
        try socket.bind(toPort: port)
        try socket.enableBroadcast(true)
        try socket.enableReusePort(true)
        try socket.beginReceiving()
    } catch let err {
        print(err)
    }

    send(message: "Received")
}

func send(message:String){
    guard let data = message.data(using: .utf8) else { return }
    socket.send(data, withTimeout: 2, tag: 0)
}

在Listener视图控制器中，我实现了didReceive委托方法，但它没有接收任何内容。是否有人可以至少帮助我处理字符串部分，以便我可以从发送方应用程序发送字符串并在接收方应用程序中接收

对于接收数据，您必须编写此方法beginReceiving（），通过此方法，如果服务器向您发送内容，您将从服务器获得响应。此方法启动接收过程，通过该过程，每当服务器发送任何内容时，您都将接收GCDAsyncUdpSocket的didReceiveData委托中的数据

  let socket = GCDAsyncUdpSocket(delegate: self, delegateQueue: DispatchQueue.main)
        do {
            try socket.connect(toHost: hostIP, onPort: port)
            try socket.beginReceiving()
        } catch let err{
            print("Error Connecting, ", err)
        }
