How to increment NSIndexPath of a UICollectionView
<p>I'm calling this method and nextCellIndexPath is an indexPath greater than the current cell, but the indexPath isn't being properly incremented.</p>

<p>Here is the cellForItemAtIndexPath:</p>

<pre><code>func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -&gt; UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("collectionViewCell", forIndexPath: indexPath) as! ImageCollectionViewCell
    cell.nextCellIndexPath = indexPath.indexPathByAddingIndex(1)
    return cell
}
</code></pre>

<p>When I try to scroll to the next indexPath, it appears that the indexPath doesn't increment.</p>

<p>So how do I correctly get the next indexPath?</p>
