iOS UITableView deleted cell contents re appear when inserting new cell

I've a table view where cells can be inserted and deleted. For insertion of cells, I use the following code:

tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: cellCount-2, section: 0)], with: .automatic)
tableView.endUpdates()

For deleting cells, I use the following code:

tableView.beginUpdates()
tableView.deleteRows(at: [indexPath], with: .automatic)
tableView.endUpdates()

Attaching the gif of the issue I face. On deleting a cell and inserting a new one, the contents of the cell gets populated in the new cell. Can someone help me sort this issue?

If you are using the standard UITableViewCell remember to reset the content inside the UITableViewDelegate function cellForRowAtIndexPath since the dequeueReusableCell will recycle an already initialized cell (that has to be brought to its original state)

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "aCellIdentifier", for: indexPath)!
    ...
    cell.title.text = ""
    cell.description.text = ""
}

A typical approach is however to subclass UITableViewCell and implement prepareForReuse method (which is called automatically before the cell being reused), where you will eventually reset all labels, images, subviews to the initial state

override func prepareForReuse() {
     super.prepareForReuse()
     self.labelScore.text = ""
     self.labelDate.text = ""
}
