UITableView implementation guide after data source changes on iPhone 15 with iOS 17
After trying multiple solutions online, I still can't figure this out. I'm experiencing an scenario where my `UITableView` fails to update after I modify the data source on an iPhone 15 running iOS 17. I have implemented the `UITableViewDataSource` methods correctly, and I’m calling `tableView.reloadData()` after updating the data source. However, the table view does not reflect these changes. Here's a simplified version of my code: ```swift class MyViewController: UIViewController, UITableViewDataSource { var items: [String] = ["Item 1", "Item 2"] @IBOutlet weak var tableView: UITableView! override func viewDidLoad() { super.viewDidLoad() tableView.dataSource = self } func updateItems() { items.append("Item 3") tableView.reloadData() } func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return items.count } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) cell.textLabel?.text = items[indexPath.row] return cell } } ``` I've verified that `updateItems()` is indeed being called, and I see the correct number of items in my array when I debug it. However, the UI remains unchanged. I also tried calling `beginUpdates()` and `endUpdates()` around my reload, but that didn’t help. When I checked for any constraints or layout issues, everything appears to be in order. Is there something specific to iOS 17 or the iPhone 15 that might be causing this behavior? Any guidance would be appreciated. This is part of a larger application I'm building. What's the best practice here?
