In the editor, you have a pretty complex dictionary representing a movie. It contains a nested dictionary, which itself contains an array of Strings as a value.
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.
Since dictionaries return optional values, you will have to use an if let statement to unwrap each consecutive operation.

if let movieTitle = movieDictionary["Spectre"], let movieCast = movieTitle["cast"] { let leadActor = movieCast[0] }

leadActor had already been declared as a variable! It should look like this:
if let movieTitle = movieDictionary["Spectre"], let movieCast = movieTitle["cast"] { leadActor = movieCast[0] }

2,108 Pointslet movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "Léa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]
var leadActor: String = ""
// Enter code below if let spectre = movieDictionary["Spectre"] { if let cast = spectre["cast"]{ if let leadActor = cast["Daniel Craig"]{ print (leadActor) } } }
