I do not understand what this code challenge is looking for? Is it the initializer statement that the function needs to be in? Do they even want this function to be created? Why do I get an error?
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String: String]) {
return nil
func bookOne(Book: [String: String]) -> Book {
guard let title = Book["title"], let author = Book["author"] else {
//return nil
}
let price = Book["price"]
let pudDate = Book["pubDate"]
return Book(title: title, author: author, price: price, pudDate: pudDate)
}
}
}

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"]
}
}
