I have no idea where I am going wrong with this code.

For the challenge task - it asks us to using the key profilePicture to retrieve the image name as a string from the dictionary and assign it to a constant named profileImageName, and then to make it into an instance. But, I seem to be missing a few crucial steps.

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {

        let friends = Treehouse().friends
        let profileImageName = treehouse["profilePicture"] as String!
  profilePicture = UIImage(named: profileImageName)

        //Add your code below


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

  var firstName: String?
  var lastName: String?
  var profilePicture: UIImage?

  init(index: Int) {
  let treehouse = Treehouse().friends
  let friendsDictionary = treehouse[index]

You're almost there, here's what worked for me, the only difference is that I didn't cast the profilePicture as String, only unwrapped it, and there was a missing "let" keyword in front of profilePicture

let profileImageName = treehouse["profilePicture"]!
let profilePicture = UIImage(named: profileImageName)
