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.
What I'm I doing wrong hear
let movieDictionary = ["Spectre": ["cast": ["Daniel CraThe ig", "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"], let lead = cast[0] {
leadActor = lead
}

First, I think you may have accidentally modified the movie dictionary value for "Daniel Craig". You may want to fix that first.
Secondly, I would suggest copying the code any pasting it into a playground in Xcode. I think the compiler error in there will lead to the answer you are looking for.
Hint: What does an if let statement unwrap?
