title: UICollectionView container padding
body: <p>I am trying to add padding to the container of a UICollectionView. I would like it to appear as such that there is a 10pt padding all around. So in the example screen, there is a 10pt padding on the bottom from:</p>
  
  <pre><code>layout.minimumInteritemSpacing = layout.minimumLineSpacing = 10;
  </code></pre>
  
  <p>I am using a UICollectionViewFlowLayout to layout the cells. I have also tried a "trick" where I add a 10pt view on top, but the content doesn't appear to scroll through the view since they are separate.<img src="https://i.stack.imgur.com/7Xl0w.png" alt="enter image description here"></p>
