I believe the Dictionary definition as Dictionary<String, String> was the issue. I changed that to [String: String] and that passed.
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
}
price = dict["price"]
pubDate = dict["pubDate"]
self.title = title
self.author = author
}
}
Let me know if that works for you!
