iOS Swift 2.0 Enumerations and Optionals Introduction to Optionals Nil Values in Collections

In a code challenge, when I hit preview it doesn't show any error yet the check says "your code could not compile", why?

When I hit the preview button I get nothing but black screen, which is a good sign actually. Then I follow up with the check work (or recheck work) button and it says that my code could not compile. Not sure what's going on here.

I attached the code, it's meant for the "Nil Values in Collections" challenge.

Thank you for your time !

optionals.swift
let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "Léa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]

var leadActor: String? = ""

// Enter code below
if let movie = movieDictionary["Specter"],
    let casting = movie["cast"]
{
    leadActor = casting[0]
}
