Help with Instances of UiImageView in Swift.

Can someone help me out with this challenge? It's just telling me make sure I use the correct key.

ImageViews.swift 
import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let friends = Treehouse().friends

        let profileImageName = friends.profilePicture

        let profilePicture = profileImageName


    }

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

if profilePicture is uiimage, then try this

let profilePicture = UIImage(named:profileImageName)

To use a key your code should look like this...

let profileImageName = friends[“profilePicture”] as String
let profilePicture = UIImage(named: profileImageName)

You have the right idea and on the right track.

Happy coding!
