Am I suppose to use a function to retrieve the values as it states in the task?
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String: String]) {
return nil
}
}
func newBook(dict: [String: String]) -> Book? {
if let title = dict["title"],
let author = dict["author"] {
let price = dict["price"], let pubDate = dict["pubDate"])
} else {
return nil } }
