Where has the code gone??

Hey guys,

at 1.50 of this video, we're shown to add code to the total price. For some reason I have code in XCODE that is missing from the code.

Specifically here:

 func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
        updateCellBackgroundColor(indexPath, selected: true)

        currentSelection = vendingMachine.selection[indexPath.row]
    ///THIS CODE ->   
 if let currentSelection = currentSelection, let item = vendingMachine.itemForCurrentSelection(currentSelection) {
            totalLabel.text = "$\(item.price)"
        }
    /// -<
    }

Where has it gone in the video? And why don't we need it anymore?

Pasan refactored that code so it is now in a function called updateTotalPriceLabel() so you don't have to copy and paste the entire code into the places you need it. Instead you just call the function.
