Question

I am implementing chat using socket and I want to get list from server using once listener of socketIO.Problem I am facing is after getting response from socket my table view is not reloading I had made delegate and datasource self using code as well as from storyboard but no success. Here is my code:
//List data Socket completion handler
SocketHelper.shared.messageChatList(recieverID ?? "0"){success,responseData,error in
if success == true{
if let arr = responseData as? [[String: Any]]{
DispatchQueue.main.asyncAfter(deadline: .now()) {
if let dataArray = arr[0]["data"] as? NSArray {
for i in 0..<dataArray.count {
if let dataDict = dataArray[i] as? NSDictionary {
let chatListModelObj = ChatListModel()
chatListModelObj.dataDict(dict: dataDict)
self.chatListModelAry.append(chatListModelObj)
}
}
}
}
print("Array Count:",self.chatListModelAry.count)
self.tblVw.delegate = self
self.tblVw.dataSource = self
self.tblVw.reloadData()
self.tblVw.layoutIfNeeded()
}
} else{
self.tblVw.reloadData()
}
}
// my table view functions
extension BusinessesChatVC: UITableViewDataSource,UITableViewDelegate{
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return chatListModelAry.count
print("chatListModelAry:",chatListModelAry.count)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cellObj = self.tblVw.dequeueReusableCell(withIdentifier: "BusinessChatTVC", for: indexPath) as! BusinessChatTVC
if chatListModelAry.count > 0 {
DispatchQueue.main.async {
let chatListModelAryObj = self.chatListModelAry[indexPath.row]
cellObj.lblRecievedMsg.text = chatListModelAryObj.message
}
}
return cellObj
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat{
return UITableView.automaticDimension
print("Dimension:",UITableView.automaticDimension)
}
}
