Test Failing: "Make sure you use the right key"

So on this task, we have to take from an instance of the Treehouse struct which contains a dictionary of friends information.

We are to create 2 constants, one called profileImageName and one called profilePicture

first one is the string representation of the profilePicture, and the second one is a UIImage of based on that name. Mine however is telling me to make sure I'm using the right key. If it's wrong, then I can't copy/paste right.

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {

        let friends = Treehouse().friends

        //Add your code below
        let profileImageName = friends["profilePicture"] as String!
        let profilePicture  = UIImage(named:profileImageName)

struct Treehouse {
    let friends = [
        "firstName": "Susan",
        "lastName": "Olson",
        "profilePicture": "susan_profile.png"
