Can someone help me find my error in my code?

Please and thank you!

ImageViews.swift 
import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let friends = Treehouse().friends

        let susan_profile.png = friends["profilePicture"] as String!
        profilePicture = UIImage(named: susan_profile.png)

        let profileImageName = susan_profile.png

        let profilePicture = profileImageName






    }

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

Hello : 

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let friends = Treehouse().friends

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


    }

}

When you use the key "profilePicture" for the dictionary, it will return a String, therefore you do not need to downcast it as you were doing.

Good luck
