2,509 PointsMay I get the answer to Challenge task 1 of 1 within the initializing optional values lesson?
what is wrong with the below that does not allow me to compile the code. The compiler gives an error but does not give suggestions. The error says that only a valid instance or nil can be returned.
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String : String]){
guard let myTitle = dict["title"], let myAuthor = dict["author"] else {
return nil
}
self.title = myTitle
self.author = myAuthor
self.price = dict["price"]
self.pubDate = dict["pubDate"]
return nil
}
}

init?(dict: [String : String]){
guard let myTitle = dict["title"], let myAuthor = dict["author"] else {
return nil
}
self.title = myTitle
self.author = myAuthor
self.price = dict["price"]
self.pubDate = dict["pubDate"]
}
// I think the "return nil" part of your code was unnecessary.
