struct Book {

let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String: String]){

    guard let title = dict["title"], author = dict["author"] else {
        return nil
    }
self.title = title
self.author = author
self.price = dict["price"]
self.pubDate = dict["pubDate"]

} }

And have no ide why these two brackets are not in code! :) This is the correct code! Enjoy :)
