I think it's personal.

In the next code challenge, the compiler won't accept my code. I've run it in a playground, stared at it for 10 minutes, tried to think of why on earth that might be and I still haven't figured it out.

The challenge says :

Your job is to assign the string containing the value for the lead actor (which for the sake of the example is at position 0 in the array) to the variable leadActor.

And this is the code : 

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

var leadActor: String = ""

// Enter code below

if let movie = movieDictionary["Spectre"], let cast = movie["cast"] {
    var leadActor: String = cast[0]
}

Can somebody give me a hint on what is it that I am doing wrong ? That'd be much appreciated.

Thank you.
