Hide view in specific CollectionViewCell

I have question how to implement this stuff in right way. So far I done

if indexPath.row == 1 {
            let indexPatha = NSIndexPath(forRow: 0, inSection: 0)

            let changeCell = collectionView .cellForItemAtIndexPath(indexPatha) as! BarCollectionViewCell
            changeCell.addNewBottleSecondButton.alpha = 0
}

But when I swipe until cell is hidden, I am getting error, unexpectedly found nil while unwrapping an Optional value, and still this doesn't looks like how I want to make it. I want to achieve that when I have more then one cell, I want to hide one specific view.

If the cell has been scrolled off the screen it may not exist anymore due to Apple's dequeue/re-use optimizations. Previously when confronted with this problem, I've had to set a state variable and handle the UI change in cellForRow if the cell didn't exist when trying to change the cell's UI.

Would it work in your flow to handle this in cellForRowAtIndexPath instead?

After your initialize your cell:

    cell.addNewBottleSecondButton.hidden = (indexPath.row == 0) && (dataItems.count > 1)
