How do I unravel the dictionary?
let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "LÊa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]
var leadActor: String = ""
// Enter code below
if let movieDictionary = movieDictionary["spectra"], if let movieDictionary = movieDictionary["cast"], let leadActor = movieDictionary[0]

Well you almost got it. All you had to do was close the if let statement with the braces and then assign the value of the array to leadActor.
if let movie = movieDictionary["Spectre"], let cast = movie["cast"] {
leadActor = cast[0]
}
Good luck

I recommend choosing one way or the other. Since cast is the last nested dictionary in the bunch, we do not have to unwrap any further. Once let movieDictionionary = ["cast"] is successfully unwrapped and stored, you can enter your code block and then update the variable for leadActor.
So something like if let spectra = ...., let spectra[cast]=... { then update the leadActor}
