collectionView

class ZeroCollectionView: UICollectionView {

convenience init() {

    let size = (UIScreen.main.bounds.width / 3)
    layout.itemSize = CGSize(width: size, height: size)
    layout.minimumLineSpacing = 0
    layout.minimumInteritemSpacing = 0
    self.init(frame: .zero, collectionViewLayout: layout)

    cell.contentView.backgroundColor = indexPath.row % 2 == 0 ? .red : .blue
