Autolayout bug on Collection View when scrolling

   func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath) as! FeedCell

    cell.setNeedsLayout()
    cell.layoutIfNeeded()

    cell.avatarImageView.image = #imageLiteral(resourceName: "avatar-1")
    cell.avatarImageView = makeImageViewRound(image: cell.avatarImageView)
    cell.avatarImageView.contentMode = .scaleAspectFill

    cell.alpha = 1

    if postList.count > 0 {
        cell.alpha = 1
        fetchAvatar(userID: postList[indexPath.row].userID!, completion: { (url) in
            cell.avatarImageView.imageFromServer(urlString: url)
        })
        cell.nameLabel.text = postList[indexPath.row].name
        cell.titleLabel.text = postList[indexPath.row].title
        cell.descriptionLabel.text = postList[indexPath.row].info
        cell.descriptionLabel.sizeToFit()
    }

    return cell
}
