title: Show the bottom of collectionView on first load without scrolling and lazy loading
body: <p>I have developed a Chat App, where I used MessageKit for my iOS app. My issues is when I open any Chat screen, messageCollectionView starts from top ,showing old chats. I need to start the collectionView from bottom as soon as I open any chat screen.
  I have tried :</p>
  
  <p>messagesCollectionView.scrollToBottom(animated: true)</p>
  
  <p>but there is a performance impact (in case there and more than hundreds/thousands of messages).</p>
  
  <p>Is there any way if inverting the collection view, or starting to add the cells from bottom and then top.</p>
