Swift 3 implementation issue

[Satheez]

Hi, i've implemented those functions. It's working on swift 2.3. But I'm having problem when using with swift 3. The issue is "xmppStream.myJID = XMPPJID.jidWithString(jabberID)". Xcode says that jidWithString is not a funtion anymore.

So could you please tell iss there any alternative to assign the jabberid?

Many thanks in advance.

[horstleung]

Xcode tell me to try XMPPJID(string: "") , not sure working or not. I am still migrating my project to Swift 3. (lots of errors, yea)

And I am facing the problem of ambiguous use of elementForName. Anyone fixed this problem with magic?

[Satheez]

hey thanks for responding..

actually I found a solution to implement xxmp with swift 3.

I'm using pod ->

pod 'XMPPFramework', :git => "https://github.com/robbiehanson/XMPPFramework.git", :branch => 'master'

And the connecting query follows > let xmppStream = XMPPStream() xmppStream?.myJID = XMPPJID.init(string: jabberID) // jabberID is your open fire username xmppStream?.hostName = "your_registered_domain" xmppStream?.hostPort = 5222 xmppStream?.enableBackgroundingOnSocket = true do { try xmppStream?.connect(withTimeout: XMPPStreamTimeoutNone)

            print("Connection success")
            return true
        } catch {
            print("Something went wrong!")
            return false

}

and you have to include all other functions like xmppStreamDidConnect, xmppStream etc

It works for me... :)

Hi there. Same problem here. I'm using swift3, but never connect to the server so i can't try to authenticate user. Never enters to xmppStreamDidConnect(), can you post your working code?

Thanks a lot

[Satheez]

Sure.. this is the app AppDelegate code. (Before everything you must setup your domain, username and password.

[AbrahamSev]

Thank you very much. I will try again to connect :)

[Satheez]

No problem,

Dont forget to call connect in the Controller

let appDelegate = UIApplication.shared.delegate as! AppDelegate // go online _ = appDelegate.connect()

All the best. 👍

Not able send messages

here it is my code to get online users

func xmppStream(_ sender: XMPPStream!, didReceive presence: XMPPPresence!) {
    let presenceType = presence.type()
    let status = presence.status()
    let myUsername = sender.myJID.user
    let presenceFromUser = presence.from().user as String

    if presenceFromUser != myUsername {
        print("Did receive presence from \(presenceFromUser)")
        print("Type \(presenceType)")
        print("Type \(status)")

            if presenceType == "subscribe" {
            delegate.buddyWentOnline(name: "\(presenceFromUser)@domainName")
        } else if presenceType == "unavailable" {
            delegate.buddyWentOffline(name: "\(presenceFromUser)@domainName")
        }
    }
}

and this way i am sending message

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    let alertController = UIAlertController(title: "Warning!", message: "It will send Yo! to the recipient, continue ?", preferredStyle: UIAlertControllerStyle.alert)
    alertController.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel, handler: { (action) -> Void in
        alertController.dismiss(animated: true, completion: nil)
    }))

    alertController.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler: { (action) -> Void in
        let message = "Yo!"
        let senderJID = XMPPJID.init(string: self.onlineBuddies[indexPath.row] as! String)
        let msg = XMPPMessage(type: "chat", to: senderJID)

        print("Sender JID %@",senderJID as Any)

        msg?.addBody(message)

        self.appDelegate.xmppStream?.send(msg)
    }))
    present(alertController, animated: true, completion: nil)
}

Please help me out, thanks in advance

[MadBurea]

hii not able to send message

As i can receive message and even know roaster availability and type whether composing or paused.

for send i have used this code let message = messageTextField.text

    var clientJid: XMPPJID!
    clientJid = XMPPJID.init(string: "Mad@700.305.150.890")
    let senderJID = clientJid
    let msg = XMPPMessage(type: "chat", to: senderJID)
    msg?.addBody(message)
    stream?.send(msg)

Here stream is XMPPStream

Please help

[MadBurea]

hii @pmehul55 Did you solved error. Have your message sent. if Yes then Plese help me

[AbrahamSev]

Hi. I already have working XMPP client, hope it helps

func sendXmppMessage(msg: String, to: String) { let toJID = to + "@" + xmpp_serverName // your server name let senderJID = XMPPJID.init(string: toJID) let xmppMsg = XMPPMessage(type: "chat", to: senderJID) xmppMsg?.addBody(msg) if xmppStream!.isAuthenticated() { xmppStream?.send(xmppMsg) }else{ msgStack.append(xmppMsg!) // Save your message for later XmppConnect() } }

This function must be coded in AppDelegate, but if you want to send xmppMessage from viewController you need to make an instance of appDelegate in your view controller first

in your view controller: let delegate = UIApplication.shared.delegate as! AppDelegate

after you instantiate your app delegate in your viewController, you can call the sendXmppMessage function:

delegate.sendXmppMessage(msg: "your message", to: "destinationBareJID")

pmehul55: And for the Roster, you should use 'available' instead of 'suscribe' to get buddies status.

Hello , i am facing same issue my xmppStreamWillConnect(_ sender: XMPPStream!) is called but xmppStreamDidConnect(sender: XMPPStream!) is never called. Connection is not established ever.

Any one help on this?

Hello Chris Ballinger,

Hope you are doing well,

Please try below code for sending message.

        let completeMessage = DDXMLElement.element(withName: "message")

as! DDXMLElement

        completeMessage.addAttribute(withName: "id", stringValue:

messageID!)

        // Group Chat Message//

         if rosterInfo.roster_type == 1 {

            completeMessage.addAttribute(withName: "type", stringValue:

"groupchat")

            let requestElement = DDXMLElement.element(withName:

"request", uri: "urn:xmpp:receipts") as! DDXMLElement

            completeMessage.addChild(requestElement)

        }else

     // One to One Chat//

        {

            completeMessage.addAttribute(withName: "type", stringValue:

"chat")

        }

          completeMessage.addAttribute(withName: "to", stringValue:

senderJID)

         let body = DDXMLElement.element(withName: "body") as!

DDXMLElement

        body.stringValue = trimmedMessage

        completeMessage.addChild(body)

        sender.send(completeMessage)

Hi @chrisballinger Thanks for reply. I accidentally found that error in my code. I have to _ before sender otherwise this method will not be called. And now my chatting is working fine.

I want to fetch element node (<about>) in message.

[ChanchalW]

Why don't you use xml parser. It will be more easy with parser rather then parsing node by node.
