Stuck with playlist challenge

In our Treehouse model struct below we have a property named friends. It is a dictionary that holds information about our friends including their profile pictures. In the ViewController class, using the key profilePicture, retrieve the image name as a string from the dictionary and assign it to a constant named profileImageName. I’ve already created an instance of the Treehouse struct and stored a reference to the friends library in a constant named friends for you to use.

Once you have the image name, create an instance of UIImage using the image name and store it in a constant called profilePicture. Who can help me with the codes?

ImageViews.swift 
import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let friends = Treehouse("profileImageName").friends

        let profilePicture = Treehouse(friends: "profileImageName")


    }

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