instance method to output string

What am I doing wrong with the firstTag such that it is not outputting "Swift"?

structs.swift 
struct Tag {
    let name: String
}
struct Post {
    let title: String
    let author: String
    let tag: Tag

    init(title: String, author: String, tag: Tag) {
        self.title = title
        self.author = author
        self.tag = tag
    }

    func description() -> String {
        let sentance = "\(title) by \(author). Filed under \(tag)"
        return sentance
    }
}
let firstTag = Tag(name: "Swift")
let firstPost = Post(title: "iOS Development", author: "Apple", tag: firstTag)

let postDescription = firstPost.description()

Hey Hunter,

You are pretty much on the right track.

At this point in your "description" function :

let sentance = "(title) by (author). Filed under (tag)"

You should change the last string interpolation to (tag.name)

This is because the "tag" is a struct and you want to get the "name" member attribute out of it.

Also since this is a Struct exercise and not a Class exercise, you don't absolutely have to do the whole "init{}" process. Hope that was useful.
