Reload tableview with UITableViewAutomaticDimension , Bounce

Today I have gone through with the very varied behaviour of the table view. It's bounce every time I call reload function as my table view cells are dynamic and having a different type of contents, so I used the property of UITableViewAutomaticDimension for row height.

So, to resolve this bounce issue on the reload function of the table. I have to store the height of the row from tableView willDisplay cell method and used the same in estimatedHeightForRowAt. Please find the code below. Hope it will help someone.

var height_OfCells = NSMutableDictionary()

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    if let height = height_OfCells.object(forKey: indexPath) {
        return height as! CGFloat
    }

    return UITableViewAutomaticDimension
}

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    height_OfCells.setObject(cell.frame.size.height, forKey: indexPath as NSCopying)
}
