I swear this is right but it won't let me pass.

I can't see anywhere it's wrong.

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 taggy = Tag(name: "ghi")
let firstPost = Post(title: "abc", author: "def", tag: taggy)
let postDescription = firstPost.description()

Hi Nicholas,

You are very close. The only mistake is that you are returning the tag struct instead of the name property of the tag.

See below.

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)" // access name property
    }
}

let taggy = Tag(name: "ghi")
let firstPost = Post(title: "abc", author: "def", tag: taggy)
let postDescription = firstPost.description()

I hope that helps,

Mike
