Cell 안에 padding 여백 동적으로 넣는법

extension CategoryCollectionView: UICollectionViewDelegateFlowLayout {

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {

        lazy var label: UILabel = {
            $0.font = .systemFont(ofSize: 14)
            $0.text = tagList[indexPath.item]
            $0.sizeToFit()
            return $0
        }(UILabel())

        let size = label.frame.size

        return CGSize(width: size.width + 20, height: size.height + 12) // 여백을 준다
    }
}
