I am having lots of problems with this challenge. I have been looking at similar questions and answers but cannot seem to find what the problem is with my code. When I try to run this in swift, the error says that "Array types are now written with the brackets around the element type...Fix It Replace "dict[" with "[dict" ". I do not understand why this is, but regardless if I let the fix happen then it pulls another error which says "Variable binding in a condition requires an initializer". Any help and explanation as to why this happens would be appreciated.
struct Book {
let title: String
let author: String
let price: String?
let pubDate: String?
init?(dict: [String: String]) {
guard let title: dict["title"], let author: dict["author"] else {
return nil
}
self.title = title
self.author = author
self.price = dict["price"]
self.pubDate = dict["pubDate"]
}
}

You almost got it! There's just a little mistake in the guard let statement: you need to assign the value to that constant, and we do so with the equal (=) parameter, not the dots (:).
guard let title = dict["title"], let author = dict["author"] else {
Hope it helps!
