Swift Recap Part 1 Challenge (Task 2 of 2) - hazy on string interpolation...[RESOLVED]

It's giving me:

Bummer! Make sure the implementation of description matches the directions. Hint: Use string interpolation!

....but I think I'm close because the output is not showing any compiler errors.

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)"
    }
}

let firstPost = Post(title: "Title", author: "Author", tag: Tag(name: "String"))
let postDescription = firstPost.description()

Got it -- (Wow..was I stupid!)

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