You want to create an UIImage with the profile picture key inside the dictionary. Since they've already provided the dictionary in the variable 'friends', I'd use that to obtain the image name.

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

I hope I've helped! :)

Just a side thought

They should of made the friend's constant a static. The way it's currently currently set up, it could potentially waste more resources than it needs.
