Swift 3 - Failing initializers

Still not sure why this is not passing.

I checked it against the Swift 2.0 version. https://teamtreehouse.com/community/i-dont-see-how-a-dictionary-thats-passed-into-the-initializer-can-contain-both-the-title-and-the-author

..and no dice.

Any input on this would be greatly helpful!

optionals.swift 
struct Book {
    let title: String
    let author: String
    let price: String?
    let pubDate: String?


    init?(dictionary: [String:String]) {

        guard let title = dictionary["title"], let author = dictionary["author"] else {
            return nil
        }

        self.title = title
        self.author = author
        self.price = dictionary["price"]
        self.pubDate = dictionary["pubDate"]

    }
}

Turns out they don't want you to use the word 'dictionary'. They would prefer you use 'dict' and then the challenge passes!
