Heya Jon,

You need to access the friends dictionary by using the key "profilePicture" and assign it to a constant named profileImageName and unwrapping String optional. Once you have the name, you instantiate the UIImage with it and assign that to a constant named profilePicture.

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

Hope this helps.

Regards,

Chris
