title: Way to dequeue multiple cells in UIcollectionview
body: <p>based on the screen shot, I will have a big collectionview to contain few cells (with colors). All cell will display only one time in the view except for the green one.The green one will display an array of users. </p>
  
  <pre><code>func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -&gt; UICollectionViewCell {
  
          if indexPath.item == 0{
              let cell = collectionView.dequeueReusableCell(withReuseIdentifier: topfeatureCellIndent, for: indexPath) as! topFeatureCell
              //configure if needed
              return cell
          }else if indexPath.item == 1{
              let cell = collectionView.dequeueReusableCell(withReuseIdentifier: userCellIdent, for: indexPath) as! featureUserContainerViewCell
              cell.featureUsers = featureUser
              cell.selectUserdelegate = self
              return cell
          }else if indexPath.item == 2{
              let cell = collectionView.dequeueReusableCell(withReuseIdentifier: ticketLabelIdent, for: indexPath) as! ticketLabelCell
              return cell
          } else if indexPath.item == 3{
              let cell = collectionView.dequeueReusableCell(withReuseIdentifier: whosgoingIdent, for: indexPath) as! whoGoingCell
              cell.config(withTimer: timeleft)
              return cell
          }
              let cell = collectionView.dequeueReusableCell(withReuseIdentifier: allUserCellIdent, for: indexPath) as! allUserCell
              let index = indexPath.item - 4
              let user = allPartyUserArr![index]
              cell.config(withUser: user)
              return cell
  </code></pre>
  
  <p>The way I need to display the last cell is by implement the code above but I think its not correct, because what if I want to add in other cells after displaying all the cells, is there any better way to dequeue the cell properly?</p>
