How to get ipAdress from NWListener and NWBrowser

NetServiceBrowser has 2 delegate functions. The first delegate gets called when it discovers a service netServiceBrowser(: didFind: moreComing: ) and the second delegate (below) gets triggered when the address is resolved. You can use that delegate to get the ipaddress:

func netServiceDidResolveAddress(_ sender: NetService) {
    print("did resolve address")

    var hostname = [CChar](repeating: 0, count: Int(NI_MAXHOST))
      
    guard let data = sender.addresses?.first else { print("guard let data failed"); return }
      
    data.withUnsafeBytes { (pointer: UnsafeRawBufferPointer) -> Void in
        let sockaddrPtr = pointer.bindMemory(to: sockaddr.self)
        guard let unsafePtr = sockaddrPtr.baseAddress else { return }
        guard getnameinfo(unsafePtr, socklen_t(data.count), &hostname, socklen_t(hostname.count), nil, 0, NI_NUMERICHOST) == 0 else {
            return
        }
    }
   
    let ipAddress = String(cString:hostname)
    print(ipAddress)
}

How can i get the ipAddress when a NWBrowser connects with a NWListener and the NWListener responds back to the NWBrowser?

Listener/Advertiser:

var listener: NWListener?
listener?.newConnectionHandler = { (nwConnection) in
    // new connection and/or data came in from Browser, what is its ipAddress?
}

Browser:

var browser: NWBrowser?
var connection: NWConnection?

browser?.browseResultsChangedHandler = { (results, changes) in
    for result in results {
        // Advertiser endpoint found, what is its ipAdress?
        print(result.endpoint.debugDescription)
    }
}

connection?.receiveMessage { (content, _, _, error) in
    if let messageData = content {
        // received data from Advertiser, what is its ipAddress?
    }
}
