ios uitableview autolayout swift

I'm experiencing an issue where my UITableView cells are not displaying the correct height when using automatic dimension calculations. I have implemented `UITableViewAutomaticDimension` along with a custom height calculation based on the content of each cell. However, when I scroll the table view, some cells appear to jump or don't resize correctly, leading to a jarring user experience. Here's the relevant code for my setup: ```swift class MyViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { @IBOutlet weak var tableView: UITableView! override func viewDidLoad() { super.viewDidLoad() tableView.delegate = self tableView.dataSource = self tableView.estimatedRowHeight = 100 tableView.rowHeight = UITableView.automaticDimension } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return items.count } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath) as! MyCustomCell cell.configure(with: items[indexPath.row]) return cell } } ``` In my custom cell, I have defined the layout like this: ```swift class MyCustomCell: UITableViewCell { @IBOutlet weak var titleLabel: UILabel! @IBOutlet weak var descriptionLabel: UILabel! func configure(with item: MyItem) { titleLabel.text = item.title descriptionLabel.text = item.description } } ``` Despite setting `estimatedRowHeight`, the cells are not resizing properly when long text is present in the `descriptionLabel`. I also added the following to ensure Auto Layout is functioning correctly: ```swift override func awakeFromNib() { super.awakeFromNib() titleLabel.numberOfLines = 0 descriptionLabel.numberOfLines = 0 } ``` I've tried calling `tableView.beginUpdates()` and `tableView.endUpdates()` after updating the data source, but it hasn't resolved the issue. Occasionally, I see warnings in the console referring to "Invalid row height" or "Layout could not be determined". What am I missing here to achieve smooth cell resizing? Any insights would be greatly appreciated! I'm working on a web app that needs to handle this.
