I am trying to update my array data and reload the tableview once user click on a cell, however, it takes three hits till the tableview reload a specific row that was selected. This problem only occur when I use (tableview.reloadRows()) but if I use (tableview.reloadData()) everything is working fine with just a single click but I don't want to reload the entire tableview. Can someone please tell me what I did wrong?

Code Block extension ViewController: UITableViewDataSource, UITableViewDelegate {
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return dummyData.count
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let todoCell = tableView.dequeueReusableCell(withIdentifier: "todoCell") as! TodoTableViewCell
        todoCell.dataLabel.text = dummyData[indexPath.row].item
        if (dummyData[indexPath.row].done == false) {
            todoCell.dataLabel.hideStrikeTextLayer()
        }else{
            todoCell.dataLabel.strikeThroughText()
        }
        todoCell.delegate = self
        return todoCell
    }
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let index = IndexPath(row: indexPath.row, section: 0)
        if dummyData[indexPath.row].done == false {
            dummyData[indexPath.row].done = true
            todoTableView.reloadRows(at: [index], with: .none)     
        }else {
            dummyData[indexPath.row].done = false
            todoTableView.reloadRows(at: [index], with: .none)
        }
    }
}

if you know what is the caused that lead me to wrap those methods with DispatchQueue.main.async{} as stated above please let me know hehe

Thanks for sharing your experience.
But unfortunately, whether enclosing with DispatchQueue.main.async{...} or not does not affect the behavior of my test project, so I have nothing to tell you right now.

Please share your info when you find something new, I will be watching on this thread.
