Hi. This code passed the challenge but when I created an instance with all the values then removed one of the optional values and Xcode crashed.
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
}
let price = dict["price"]
let pubDate = dict["pubDate"]
self.author = author
self.title = title
self.pubDate = pubDate
self.price = price
}
}
