Hello again :)
I have another question.
Why Type casting for Keys of Dictionaries don't work
enum Key {
case one
}
let dict: [ AnyHashable : Any ] = [ Key . one : "Hello" ]
let unwrap: [ Key : Any ] = dict as ! [ Key : Any ] // error

It's because AnyHashable is not an existential like Any but a value type (I believe it was a struct) which erases the type restriction from your Hashable type. Simply look up AnyHashable.
