        let cell : UniversalNewChatUsersCell = collectionView.dequeueReusableCell(withReuseIdentifier: "UniversalNewChatUsersCell", for: indexPath) as! UniversalNewChatUsersCell

        cell.lblUsername.text = self.arrSelectedUsersToChat.object(at: indexPath.row) as? String

        cell.layoutSubviews()
        return cell

You can get cell by calling cellForItem of collectionview. Write the code in sizeForItemAt method 

if let collectionViewCell = collectionView.cellForItem(at: indexPath) as? YourCollectionViewCell {
}

Do following in collectionViewLayout method:

if let myCell = collectionView.cellForItem(at: indexPath) as? UniversalNewChatUsersCell             
    print(myCell)
}
