Horizontal list that scrolls

Question

I'm trying to create the following view attached. Notice how there is a list of categories where there are 5 categories in each row and the whole thing scrolls horizontally. Here's how I'm going about doing it

Creating the collection

  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
    }
}

Any help would be greatly appreciated.
