How to return a valid instance here?

The code itself works in Xcode by the way

optionals.swift 
struct Book {
    let title: String
    let author: String
    let price: String?
    let pubDate: String?

    init?(dict: [String:String]) {
        if let title = dict["title"] {self.title = title}
        if let author = dict["author"] {self.author = author}
        if let price = dict["price"] {self.price = price}
        if let pubDate = dict["pubDate"] {self.pubDate = pubDate}
        return nil
    }


}
