ios uicollectionview swift

I've hit a wall trying to I'm encountering an issue with my UICollectionView not displaying custom cells correctly on an iPhone 13 running iOS 16..... The cells seem to be missing their content and layout. Here’s a snippet of my code: ```swift class CustomCollectionViewCell: UICollectionViewCell { @IBOutlet weak var titleLabel: UILabel! @IBOutlet weak var imageView: UIImageView! override func awakeFromNib() { super.awakeFromNib() // Initialization code } } class ViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource { @IBOutlet weak var collectionView: UICollectionView! var data = ["Item 1", "Item 2", "Item 3"] override func viewDidLoad() { super.viewDidLoad() collectionView.delegate = self collectionView.dataSource = self collectionView.register(UINib(nibName: "CustomCollectionViewCell", bundle: nil), forCellWithReuseIdentifier: "CustomCell") } func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return data.count } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCollectionViewCell cell.titleLabel.text = data[indexPath.item] cell.imageView.image = UIImage(named: "placeholder") return cell } } ``` The issue arises when I run the app: the cells appear, but the `titleLabel` displays as nil, and the `imageView` shows the placeholder image only on some cells. I've checked that the IBOutlet connections in the storyboard are correct, and I've tried cleaning the build and resetting the simulator, but the issue persists. I suspect it might be related to how the cells are being reused or how the layout is calculated, but I’m unsure how to debug this effectively. Any insights into what could be causing this behavior, or any best practices I should be following to resolve this issue? What would be the recommended way to handle this? For context: I'm using Swift on Debian. Am I missing something obvious?
