Bummer! Make sure you're unwrapping the value you obtain from the dictionary and double check your syntax!

Putting in 

let friends = Treehouse().friends
let profileImageName = friends["profilePicture"]
let profilePicture = UIImage(named: profileImageName)

Gives you "Bummer! Make sure you're unwrapping the value you obtain from the dictionary and double check your syntax!" This is because you are not converting the value of the UIImage to a string. You need to add as String at the end.

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