I think that on line 16 of the playground there is a filter method call missing.

let olderPlayers = playerAges.filter({ $0 > 12 }).count

It would be convenient if the downloadable materials were edited accordingly.

Hi @armdevp - this is actually some leftover code due to a last minute change in what shipped with Swift 5 - the count(where:) method was removed! I do hear it is supposed to return in Swift 5.1. I have already submitted an updated playground fo posting to the page for screencast, so it should be there soon. Thanks for bringing this to our attention, and thanks for watching!
