No, You shouldn't my friend! This is a serious mistake for the Swift example. Example designed as a non-optional, but the Test case was written with an optional scenario. So, must be one or another, not both.

*** PLEASE, URGENT HELP ***

Everything depends on this question on earth right now!

Note: I was planning to listen to the "Rihanna - Diamonds" but now I'm listening to the "The Cardigans - Nil" song.

Thank you for your comment. I updated with the easy solution after thinking mathematically. And it worked like a charm.

Best.

I passed the Test, but when I attempt my answer I got an error:

main.swift:32:11: warning: variable 'randomStreet' was never mutated; consider changing to 'let' constant
var randomStreet: Int = 0
~~~ ^
let
Fatal error: Unexpectedly found nil while unwrapping an Optional value: file test/solution.swift, line 18

This code not in the test cases. So I can't send my correct answer to the site.
