This is another of those “guess the exact wording in the suggested solution”. There’s no point to these kinds of overly strict checks.

This does not let me continue to the next task:

let allCards: (Int) → Int = { card in
return card

Because this is the only accepted solution:

let allCards = { (card: Int) → Int in
return card

Step one says there is an Int named “value” but when checking the solution there is nothing named “value”.

Also, this part of the handValue func is confusing (Int) → Int) → Int. I thought the second to last Int should have been the last one. Haaalp.
