playlist challenge

Hi i can't seem to work out the answer, i find the question quite strange strange of the bat, as it seems to be in the viewdidload method,

can't really work out what I'm doing wrong, i have followed the walk through and funnily enough have the playlistbroswer working fine.

ImageViews.swift 
import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let friends = Treehouse().friends

       let profileImageName = playListDictionary["profilePicture"] as! String!
        profilePicture = UIImage(named: profileImageName)

    }

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

You need to take out the "!" after as and put a "let" before the constant "profilePicture"

Like this: let profileImageName = playListDictionary["profilePicture"] as String! let profilePicture = UIImage(named: profileImageName)
