18,211 PointsDon't understand the init? exercise
Tried it with guard and some others but it says as error that I either have to do behind the non optionals an ! or ? (self.title = dict["title"]! or self.title = dict["title"]!) Can you help me out here?
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
}
