let profileImageName = friends["profilePicture"]!
let profilePicture = profileImageName
To get the name of the picture you get the string from the array with a normal array call with a key name. Then you only have to set the constant to the picture name.
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.
