UICollectionViewCell not updating after data source change in iOS 16
Does anyone know how to I'm facing an issue with my `UICollectionView` where the cells are not updating after I modify the data source. I'm using Swift 5 and targeting iOS 16. The collection view is displaying items correctly on the first load, but when I change the underlying data array and call `collectionView.reloadData()`, the cells don't reflect the new data. Here’s a simplified version of my code: ```swift class MyViewController: UIViewController, UICollectionViewDataSource { var items = [String]() @IBOutlet weak var collectionView: UICollectionView! override func viewDidLoad() { super.viewDidLoad() collectionView.dataSource = self loadData() // Load initial data } func loadData() { items = ["Item 1", "Item 2", "Item 3"] collectionView.reloadData() // This works fine initially } func updateData() { items = ["New Item 1", "New Item 2"] // New data collectionView.reloadData() // This does NOT update the UI } func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return items.count } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "MyCell", for: indexPath) cell.textLabel.text = items[indexPath.item] // Assuming cell has a textLabel property return cell } } ``` I call `updateData()` from a button action and expect the collection view to reload with the new items. However, the cells remain unchanged. I've confirmed that `items` is being updated correctly, as I printed the array to the console after calling `updateData()`, and it shows the new data. I’ve also verified that the `collectionView` is properly connected in the storyboard. I have tried calling `collectionView.layoutIfNeeded()` after `reloadData()`, but that didn't help either. Any thoughts on why the UI is not reflecting the data changes? Is there something specific to iOS 16 that I might be missing? This is my first time working with Swift LTS. Has anyone dealt with something similar?
