Ahhh...! Thank you, jcorum..! I thought that was too specific to one particular enum and so didn't get it. Thanks.

I struggled with this one as well. I found this page in the swift standard library.

https://developer.apple.com/reference/swift/optional

It explains the none and some cases.

Happy Coding.
