title: Swift 4 - Collection View Apply Section insets to header?
body: <p>I am using a Collection View and I am able to add Section insets to the cells inside the collection view, but it appears not to be applying to the Collection Views reusable view, is there away to set section insets for reusable views?</p>
  
  <pre><code>func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -&gt; UICollectionReusableView {
  
  
          if(kind == UICollectionView.elementKindSectionFooter)
          {
              let footerView = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "ReviewsFooter", for: indexPath) as! ReviewFooterCell
  
              footerView.reviewFooterDelegate = self
  
              return footerView
          }
          else if(kind == UICollectionView.elementKindSectionHeader)
          {
              let headerView = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "ReviewHeader", for: indexPath) as! ReviewHeaderCell
  
              headerView.totalReviews.text = "Total Reviews: " + String(self.reviews.count)
  
              return headerView
          }
  
          fatalError()
  
      }
