Надежный и правильный способ непрерывного получения данных из UDP-соединения IOS Swift ⇐ IOS

[Anonymous]

Я пытаюсь создать прослушиватель дрона на своем устройстве и получать данные от дрона через соединение UDP, но проблема в том, что когда я начинаю прослушивать порт, куда дрон отправляет данные, он может прочитать данные только один раз. после этого я получаю кучу журналов, которые не знаю, что это такое.
Я никогда не реализовывал сокет UDP в IOS, поэтому, пожалуйста, помогите мне.
мой текущий код

import UIKit
import Network

class ViewController: UIViewController {

private var listener: NWListener?

override func viewDidLoad() {
super.viewDidLoad()
startUDPListener()
}

private func startUDPListener() {
do {
let port: NWEndpoint.Port = 14550
listener = try NWListener(using: .udp, on: port)

listener?.stateUpdateHandler = { state in
switch state {
case .ready:
print("UDP Listener ready on port 14550")
case .failed(let error):
print(" Listener failed:", error)
default:
break
}
}

listener?.newConnectionHandler = { [weak self] connection in
print(" New UDP connection")
self?.receive(on: connection)
connection.start(queue: .main)
}

listener?.start(queue: .main)

} catch {
print(" Failed to start UDP listener:", error)
}
}

private func receive(on connection: NWConnection) {
connection.receiveMessage { [weak self] data, context, isComplete, error in
if let data = data, !data.isEmpty {
print("Received \(data.count) bytes")

// Example: raw bytes
print(data as NSData)

// TODO: Decode MAVLink / custom protocol here
}

if error == nil {
self?.receive(on: connection)
}
}
}

deinit {
listener?.cancel()
}
}

Я получаю всю эту кучу журналов, но не данных??
