I get 'Bummer' when I check my solution but it works in my playground & no errors show when I click Preview

My solution works in my Swift playground.

When I click to check my work I get 'Bummer' but no error info appears in the error panel

optionals.swift 
struct Book {
    let title: String
    let author: String
    let price: String?
    let pubDate: String?
    init?(parms: [String:String]) {
        guard let title = parms["title"], let author = parms["author"] else {
            return nil
        }
        let price = parms["price"]
        let pubDate = parms["pubDate"]
        self.title = title
        self.author = author
        self.price = price
        self.pubDate = pubDate
    }
}

Oh, instruction require the parm name be "dict". I think that will fix it. :(
