'Invalid update: invalid number of rows in section 0

You need to remove the object from your data array before you call deleteRowsAtIndexPaths:withRowAnimation:. So, your code should look like this:

// Editing of rows is enabled- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {    if (editingStyle == UITableViewCellEditingStyleDelete) {        //when delete is tapped        [currentCart removeObjectAtIndex:indexPath.row];        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];    }}

You can also simplify your code a little by using the array creation shortcut @[]:

[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];

Swift Version --> Remove the object from your data array before you call

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {    if editingStyle == .delete {        print("Deleted")        currentCart.remove(at: indexPath.row) //Remove element from your array         self.tableView.deleteRows(at: [indexPath], with: .automatic)    }}

In my case issue was that numberOfRowsInSection was returning similar number of rows after calling tableView.deleteRows(...).

Since this was the required behaviour in my case, I ended up calling tableView.reloadData() instead of tableView.deleteRows(...) in cases where numberOfRowsInSection will remain same after deleting a row.
