title: iOS UICollectionView inside UITableViewCell
body: <p>I want to implement a list containing several images grouped together like in the following mockup. The number of images to display in each section is dynamic and may vary. I also all images in a section to be always visible (without having to scroll horizontally or vertically).</p>
  
  <p><img src="https://i.stack.imgur.com/7QJnJ.png" alt="enter image description here"></p>
  
  <p>What is the best approach to achieve this? I was making some tests with UICollectionView inside UITableViewCell but I can't make UICollectionView/UITableViewCell size expand automatically depending on the number of images inside. 
  Is UICollectionView/UITableViewCell the way to go or is there a simpler approach?</p>
