How do you use a struct in string interpolation?

I can't figure out how to make the String Interpolation for this code challenge work given that one of the stored properties has to be a struct. See code below. Can anyone give me a hint?

structs.swift
struct Tag {
    let name: String
}

struct Post{
    let title: String
    let author: String
    let tag: Tag

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

let firstTag = Tag(name: "Name")
let firstPost = Post(title: "My First Post", author: "Ian", tag: firstTag)

let postDescription = firstPost.description()
