Courses Plus Student 5,461 PointsAssigning a New Value to a Global Variable from an Optional Chain
Hi,
I think I correctly retrieved the value that this Code Challenge is asking for, but I can't figure out how to update the value of leadActor outside of the 'if let' statement. It seems like a basic thing I'm forgetting with how to update stored properties, but I cannot figure it out. What am I doing wrong?
Thanks, Chase
let movieDictionary = ["Spectre": ["cast": ["Daniel Craig", "Christoph Waltz", "LÊa Seydoux", "Ralph Fiennes", "Monica Bellucci", "Naomie Harris"]]]
var leadActor: String = ""
// Enter code below
if let movieName = movieDictionary["Spectre"], let castList = movieName["cast"] {
var leadActor = castList[0]
}

5,026 PointsChase It looks like you're trying to create a new variable called leadActor instead of updating the variable that's already been declared above.
Example consider the following code:
var x = 2
Let's say you wanted to update the value of x to 3. You wouldn't declare a new variable named x and set it to 3, you would just type:
x = 3
Hope this helps!
