5,512 PointsWhy am I getting error message "Make sure you are retrieving the string at index 0 in the nested array?" I think I am.
The following and attached code is retrieving the string in the correct position in the dictionary. I do not understand why I am getting error "Make sure you are retrieving the string at index 0 in the nested array"
let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "Léa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]
var leadActor: String = ""
if let movie = movieDictionary["Spectre"], let castList = movie["cast"] { let leadActor = castList[0] }
let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "Léa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]
var leadActor: String = ""
if let movie = movieDictionary["Spectre"], let castList = movie["cast"] {
let leadActor = castList[0]
}

8,306 Pointsby saying "let leadActor = castList[0]" you are declaring a new constant called leadActor inside the scope of that statement. "var leadActor" is still set to "", which is the one you are trying to change
