XMPP connect will error connection-timeout

[Imanmf]

hello, everybody, I am using XMPPFramework and i can't connect to the server. I have this error : stream:error xmlns:stream="http://etherx.jabber.org/streams" connection-timeout xmlns="urn:ietf:params:xml:ns:xmpp-streams" text xmlns="urn:ietf:params:xml:ns:xmpp-streams" lang="en">Idle connection

this is my code :

import UIKit import XMPPFramework

class ViewController: UIViewController, XMPPStreamDelegate {

var stream:XMPPStream!
var xmppRoster: XMPPRoster!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    let xmppRosterStorage = XMPPRosterCoreDataStorage()
    xmppRoster = XMPPRoster(rosterStorage: xmppRosterStorage)

    stream = XMPPStream()
    stream.addDelegate(self, delegateQueue: .main)
    xmppRoster.activate(stream)

    stream.hostPort = 5222
    stream.myJID = XMPPJID(string: "emad@chat.myaddress.net")

    do {
        print("start connect")
        try stream.connect(withTimeout: 30)
        print("request sent")
    }
    catch {
        print("catch")

    }

    let button = UIButton()
    button.backgroundColor = UIColor.red
    button.setTitle("SendMessage", for: .normal)
    button.frame = CGRect(x: 10, y: 100, width: view.bounds.width - 20, height: 40)

    msg?.addBody(message)
    stream.send(msg)

I have problem with the first step. connecting to server

[Ogerets]

I don't see stream.hostName specified. Only stream.hostPort.

I don't see stream.hostName specified. Only stream.hostPort.

Thank you for answer. I set both but it's the same error.

    stream.hostName = "chat.gahvare.net"
    stream.hostPort = 5222
    stream.myJID = XMPPJID(string: "emad@chat.gahvare.net")

My swift version is 5 and my target is ios 10

Finally, I fixed my issue. I add dd DDLog.add(DDTTYLogger.sharedInstance) to my codes and i get more information. I used web functions to connect and this has a problem. func xmppStreamDidConnect(sender: XMPPStream!) { ... } it was in the document. so I write this function again. but it was changed in swift 4. so new code was like this: func xmppStreamDidConnect(_ sender: XMPPStream) { ... } so, second function (ew function) has not "!" symbol after XMPPStream. So Swift thought of the second function as a new one. not override for did connect function. so when I was connected to the server, server was waiting for me and my function didn't anything and i had an error with idle connection message
