slight change needed in the finalLayoutAttributesForDisappearingItemAtIndexPath in the challenge.

Item 3 should be: if indexPaths.contains(itemIndexPath)

@daver235, This is the newer swift syntax that wasn’t available when the tutorial was produced.

I also used a guard statement to avoid nesting like so:

attrs?.size = CGSizeZero
attrs?.alpha = 1
attrs?.center = collectionView?.center ?? CGPointZero

return attrs
