if let statement
Not sure why not working ...
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.
