4,223 PointsI don't understand why this is incorrect
As per title - I'm unclear as to why I am getting an error with this initializer.
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 = price
self.pubDate = pubDate
}
}

you need to retrieve the values for the optional properties price & pubDate
Keep working!
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"]
}
}
