No last property for "set" any more?

The book I've read claims that "You can use the first and last properties, which return one of the elements in the set".

However, I've tried it and seems it is not working. I would very appreciate if someone can explain it for me.

You can revert it back to Array which has last property. Do it this way:

let last = Array(Set([1, 2, 3, 4, 5])).last

You cannot ask for the last item of a Set. Indeed, a Set is not ordered, so there is not last item (nor last property).

Don't hesitate to take a look at the Swift Doc on Set.

If you want to find the last element, you need an ordered collection like an Array:

var myArray = [1, 2, 3, 4, 5]
print(myArray.last) // Display 5
