I am using func xmppStream(_ sender: XMPPStream, didReceive presence: XMPPPresence) for managing online offline status.This function is working fine for one to one user but it will not working properly on multiple user.

for example I have 3 user A, B and C now the scenario is Online offline status is working fine for A to B and B to A as func xmppStream(_ sender: XMPPStream, didReceive presence: XMPPPresence) function is calling very well. but If C user check status of A or B then func xmppStream(_ sender: XMPPStream, didReceive presence: XMPPPresence) is not being called.

I won't be able to understand what is the issue. Here is my Code:

func xmppStream(_ sender: XMPPStream, didReceive presence: XMPPPresence) {

    let presenceType = presence.type

    let myUsername = sender.myJID?.user



    print("myusername (myUsername)")



    if let usr = presence.from?.user {



        print("didReceive :- (presenceType)")

        print("didReceive usr :- (usr)")



        if usr != myUsername {

            if presenceType == "available" {

                let dict: NSDictionary = ["presenceType":"1",

                                          "user_id":usr]

                if !APP_DELEGATE.arrPresentUser.contains(dict) {

                    APP_DELEGATE.arrPresentUser.add(dict)

                }

            } else {

                let pred : NSPredicate = NSPredicate(format: "user_id = %@", usr)

                let approvalRequestArray =  APP_DELEGATE.arrPresentUser.filtered(using: pred) as NSArray

                if approvalRequestArray.count > 0 {

                    let dict = approvalRequestArray.object(at: 0) as! NSDictionary

                    APP_DELEGATE.arrPresentUser.remove(dict)

                }

            }

            NotificationCenter.default.post(name: Notification.Name("ReceivedUserStatus"), object: nil)

        }

    }

}

Note: I had tried to use @objc also.(@objc func xmppStream(_ sender: XMPPStream, didReceive presence: XMPPPresence))

If you want to check presence of particular user, use this.

  let query = XMLElement(name: "query", xmlns: "jabber:iq:last")

  let iq = XMPPIQ(type: "get", to: "User's JID here", elementID: xmppStream.generateUUID, child: query)

  self.xmppStream.send(iq)

Get the presence in delegate method.

  func xmppStream(_ sender: XMPPStream, didReceive iq: XMPPIQ) -> Bool {

    if iq.isResultIQ {

      print(iq.from?.user)

      print(iq.lastActivitySeconds())

    }

  }

I have solved my problem by adding following code

    let userReceiverJID = XMPPJID(string: "(receiverJID)@(CHATHOST)")



    APP_DELEGATE.xmppRoster.acceptPresenceSubscriptionRequest(from: userReceiverJID!, andAddToRoster: true)

    APP_DELEGATE.xmppRoster.subscribePresence(toUser: userReceiverJID!)
