Looking at the code challenge, it says you get a dictionary named dict as input for your init method. In your code you are also writing the dictionary parameters as input. Just for an explanation, this dictionary might be something like this:
let dictionary = ["title" : "someTitle", "author" : "someAuthor",
"price" : "anyPrice", "pubDate" : "someDate"]
This way, when you write
init?(dict: [String : String])
you already got those title, author, price and pubDate in the dictionary dict
The challenge wants you to practice the guard let statement for those declared properties (title and author) that are not optionals.
Keep up the hard work!
