Cocoa:如何在Swift中获取广播IP地址？

import Foundation

guard let socket = try? DatagramSocket(type: .udp) else {
    print("Failed to create UDP socket")
    return
}

let port: UInt16 = 8888 // 替换为你需要的端口号
do {
    try socket.listen(on: port)
    print("Socket is listening on port \(port)")
} catch {
    print("Failed to bind socket to port \(port): \(error)")
    return
}

do {
    let (data, _, sourceAddress) = try socket.readDatagram()
    let message = String(data: data, encoding: .utf8)
    print("Received message: \(message ?? "") from \(sourceAddress)")
} catch {
    print("Failed to receive message: \(error)")
}
