Ios 滚动的水平列表

我正在尝试创建以下附加视图。请注意，这里有一个类别列表，其中每行有5个类别，整个内容水平滚动。下面是我将如何做的

创建集合

  private let collectionView: UICollectionView = {
        let viewLayout = UICollectionViewFlowLayout()
        let collectionView = UICollectionView(frame: .zero, collectionViewLayout: viewLayout)
        collectionView.backgroundColor = .white
        return collectionView
    }()

        collectionView.allowsMultipleSelection = true
        collectionView.allowsSelection = true
        collectionView.dataSource = self
        collectionView.delegate = self
        collectionView.register(CategoryMiniCell.self, forCellWithReuseIdentifier: CategoryMiniCell.identifier)


extension ExploreViewController: UICollectionViewDelegateFlowLayout {
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        
        let width = itemWidth(for: view.frame.width, spacing: LayoutConstant.spacing)
        
        return CGSize(width: width, height: 44)
    }
    
    func itemWidth(for width: CGFloat, spacing: CGFloat) -> CGFloat {
        let itemsInRow: CGFloat = 5
        
        let totalSpacing: CGFloat = 2 * spacing + (itemsInRow - 1) * spacing
        let finalWidth = (width - totalSpacing) / itemsInRow
        
        return floor(finalWidth)
    }
    
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
        return UIEdgeInsets(top: LayoutConstant.spacing, left: LayoutConstant.spacing, bottom: LayoutConstant.spacing, right: LayoutConstant.spacing)
    }
    
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return LayoutConstant.spacing
    }
    
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
        return LayoutConstant.spacing
    }
}
