Value does not get assigned

Hi,

I'm trying to assign the string "Daniel Craig" to the leadActor value. It's like I can assign it inside the function, but then I try to print the constant and it's not propagating outside the function.

What should I do ?

optionals.swift 
let movieDictionary = [
    "Spectre": [
        "cast": [
            "Daniel Craig",
            "Christoph Waltz",
            "LÊa Seydoux",
            "Ralph Fiennes",
            "Monica Bellucci",
            "Naomie Harris"
        ]
    ]
]

var leadActor: String = ""

if let movieTitle = movieDictionary["Spectre"], let casting = movieTitle["cast"] {
    var leadActor: String = casting[0]
}

Hi there! You're really close here, but you're redefining the leadActor variable. It was declared outside the if let statement but inside the code block there, you're defining it again, which means it will be local to that statement.

This is what you're looking for:

//if these assignments were successful set the leadActor variable to this
leadActor = casting[0]

Hope this helps! :sparkles:
