How can we add a button over collection view using swift?
<p>I have a <code>UICollectionViewController</code> in my <code>main.storyboard</code>.<br>
I want to add a circle button to redirect to new page, But in <code>storyboard</code> is it possible to drag a button over <code>UICollectionView</code>? I don't know about footer how can we achieve.</p>

<p>It should looks like <code>UICollectionView</code> is scrolling and button will be over the collection view, I mean no effect on button.</p>
