func fetchMessageConversation()  {

    // Initialize Fetch Request

    let fetchRequest = NSFetchRequest<NSFetchRequestResult>()

    let managedObjectContext = self.appDelegate.xmppMessageArchivingCoreDataStorage.mainThreadManagedObjectContext

    // Create Entity Description
    let entityDescription = NSEntityDescription.entity(forEntityName: "XMPPMessageArchiving_Message_CoreDataObject", in: managedObjectContext!)

     // Create predicate //

    let resultPredicate = NSPredicate(format: "bareJidStr like %@", bareJidStr)
    fetchRequest.predicate = resultPredicate

    // Configure Fetch Request
    fetchRequest.entity = entityDescription
    var resultAry : NSArray!

    do {
    resultAry = try managedObjectContext?.fetch(fetchRequest) as NSArray!
    //print(result as Any)


    for i in 0..<resultAry.count {

        let messageDetails = resultAry.object(at: i) as? XMPPMessageArchiving_Message_CoreDataObject

        if (messageDetails?.body != nil) {

            let composeMsgDic = NSMutableDictionary ()
            composeMsgDic.setValue(messageDetails?.isOutgoing, forKey: "isOutgoing")
            composeMsgDic.setValue(messageDetails?.timestamp, forKey: "time")
            composeMsgDic.setValue(messageDetails?.body, forKey: "message")
            composeMsgDic.setValue(messageDetails?.message.elementID(), forKey: "messageID")
            MsgconversationAry.add(composeMsgDic)

        }



    }

     } catch {

        let fetchError = error as NSError
            print(fetchError)
    }

}
