2,747 PointsI understand most of this, but will someone explain the last part?
This is the correct answer in which i got from another post on the forum. I understand most of this up till it says self.price = dict["price"] self.pubDate = dict["pubdate"]
Why do we have to specify those strings?
Thanks
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String: String]) {
guard let title = dict["title"], author = dict["author"] else {
return nil
}
self.title = title
self.author = author
self.price = dict["price"]
self.pubDate = dict["pubDate"]
}
}

//for example
var dict: [String: String] = ["price": "$1.99", "pubDate": "1999"]
dict["price"]
//returns "$1.99"
