Problems with the Tag type

In this code underneath I want the postDescription constant to equal "Test by Tester. Filed under Dunno. But when I write the code in xcode it keeps returning "Test by Tester. Filed under Tag(name: "Dunno")"

What am I doing wrong when refering to tag?

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: "Test", author: "Tester", tag: Tag(name: "Dunno"))

let postDescription = firstPost.description()

Hi Martin.

Should the string interpolation for tag in the description function return tag.name instead of the tag object?

Something like

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

Hope this helps
