Why does my code work in playground but doesn't work for the challenge?

I don't see what I'm doing wrong here?

structs.swift 
struct Tag {
    let name: String
}

struct Post {

    let title: String
    let author: String
    let tag: Tag



    func description() -> String {
        return "\(title), by \(author). Filed under \(tag.name)"

    }

}

let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: Tag(name: "Swift"))
let postDescription = firstPost.description()

You accidentally added an extra "," here

(title),

it should be:

 return "\(title) by \(author). Filed under \(tag.name)"
