tableView reloadData/reloadRowsAtIndexPaths causes scroll flickering

I have a tableView with custom prototype cells with 50 rows. On Load more click, next 50 records should be loaded.

Now the first 50 records are scrolled smoothly, but on load more call, I call reloadData on tableView. Now the tableView scrolling is not smooth. I logged the indexes, I get the following log when I continously scroll upwards:

 index: 44
index: 43
index: 48
index: 49
index: 44
index: 43
index: 42
index: 47 // scrolls back causing flicker
index: 48

I also tried reloadRowsAtIndexPaths, still the same.

How do I solve this? Where am I getting wrong? I am using autolayout, is it causing the issue?

edited code

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cellProp" forIndexPath:indexPath];

//assign cell content

    return cell;
}

try: 

let cell = tableView.dequeueReusableCellWithIdentifier("yourCellIdentifier", forIndexPath: indexPath)

And You should not tableview.ReloadData() when load more. Using: 

tableView.insertRowsAtIndexPaths([indexpaths], withRowAnimation: UITableViewRowAnimation.Left)
