In the editor, you have a struct named Book which has few stored properties, two of which are optional.
Your task is to create a failable initializer that accepts a dictionary of type [String : String] as input and initializes all the stored properties. (Hint: A failable init method is one that can return nil and is written as init?).
Use the following keys to retrieve values from the dictionary: "title", "author", "price", "pubDate"
Note: Give your initializer argument the name dict
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String : String]){
guard let titl = dict["title"], let auth = dict["author"] else {
return nil
}
return Book(title: dict["title"], author: dict["author"], price: dict["price"], pubDate: dict["pubDate"])
}
}
