Am I even close?
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String : String])
{
guard let self.title = dict["title"], let self.author = dict["author"], let self.price = dict["price"], let self.pubDate = dict["pubDate"]
else { return nil }
}
}

With that in mind, your also doing an init statement, so you need to finish assigning these values after you verify the constants with the guard statement. I don't think you need the price in the guard as that is an optional. And then don't forget your actual assignments.
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String:String]) {
guard let title = dict["title"], let author = dict["author"] else {
return nil
}
self.title = title
self.author = author
self.price = dict["price"]
self.pubDate = dict["pubDate"]
}
}
