Dear members and Apple) I'm try to make Carousel with PageControl by UIKit with One cell at a time with scrolling, Center it in the middle, at the same time Image must be smaller then CollectionView width, and I don't want to use any Pods (iCarousel also) or SwiftUI. (PageControl I haven't connected yet in code) I watched a tons of articles, video and questions (also on Stackoverflow). I don't have much time((( And I'm sure it helps a lot of people, because I've seen many questions like my, without correct answers( Must be simple decision! 🙏🏼🙏🏼🙏🏼 What should I add to my code, give a hint, please? Here is my result (.gif) link on GIF My CollectionView code: class TopGalleryCollectionView: UICollectionView, UICollectionViewDelegate, UICollectionViewDataSource { var channels: [TopGalleryModel] = [] init() { let layout = UICollectionViewFlowLayout() layout.scrollDirection = .horizontal super.init(frame: .zero, collectionViewLayout: layout) backgroundColor = #colorLiteral(red: 0.113761507, green: 0.1048973277, blue: 0.150441885, alpha: 1) delegate = self dataSource = self register(TopGalleryCollectionViewCell.self, forCellWithReuseIdentifier: TopGalleryCollectionViewCell.reuseId) translatesAutoresizingMaskIntoConstraints = false layout.minimumLineSpacing = Constants.galleryMinimumLineSpacing contentInset = UIEdgeInsets(top: 0, left: Constants.leftDistanceToView, bottom: 0, right: Constants.rightDistanceToView) showsHorizontalScrollIndicator = false showsVerticalScrollIndicator = false isPagingEnabled = true } required init?(coder: NSCoder) { fatalError("init(coder:) has not been implemented") } // MARK: - Data Source func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return channels.count } func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let cell = dequeueReusableCell(withReuseIdentifier: TopGalleryCollectionViewCell.reuseId, for: indexPath) as! TopGalleryCollectionViewCell cell.mainImageView.image = channels[indexPath.row].coverImage cell.nameOfChannel.text = channels[indexPath.row].nameOfChannel cell.numberOfSubscribers.text = channels[indexPath.row].numberOfSubscribers return cell } // MARK: - Filling with content func setContentFor(channels: [TopGalleryModel]) { self.channels = channels } } extension TopGalleryCollectionView: UICollectionViewDelegateFlowLayout { func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize { return CGSize(width: Constants.galleryItemWidth, height: frame.height) } } Thanks in advance dear colleagues!)
