i am confused i thought i did this correctly?

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 uner \(tag)"
    }
}

let firstPost = Post(title: "My Coding Progress", author: "Tyler Dotson", tag: Tag(name: "T-Dot"))
let postDescription = firstPost.description()

First of all, slight typo on the return of the description function "Filed under" :).

You also need to specify the correct arguments when creating an instance on Post. (title: "iOS Development", author: "Apple", tag: Tag(name: "swift")) as per the challenge requirements.

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)"
    }
}

let firstPost = Post(title: "iOS Development", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()

Hope that helps

the apple thing is just an example. it doesn't pass. what it wants is in the description method, instead of tag, you need to reference tag's attribute, name, using dot notation, so tag.name.
