title: Swift Dynamic CollectionView Height: CollectionView inside CollectionViewCell
body: <p>I have collectionView(list of items) inside another collectionview(list of items) and base on inside collectionview's content size we have set that to parent collection(cell)</p>
  <p>Below is the scenario<br />
  <code>Parent CollectionView &lt;br/&gt; // **Parent Collection**</code></p>
  <p><code>  CollectionViewCell</code></p>
  <p><code>    Child CollectionView // **child Collection**</code></p>
  <p><code>      CollectionViewCell</code></p>
  <p>I have to set Content Size(child) to parent CollectionView Height</p>
  <p>we don't want to use observer inside collectionview cell for contentSize changed</p>
  <p>Thanks in Advance</p>
