help with optional unbinding

Am I suppose to use a function to retrieve the values as it states in the task?

optionals.swift 
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 } }
