For whatever reason I don't match the description specified in the challenge.

Where is my Error to match the description?

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: "iOSDevelopment",author: "Apple", tag: Tag(name: "swift"))

let postDescription = firstPost.description()

Hi Tomas,

You want to access the tag instance's "name" property. so make sure that in the description method, you ask for "tag.name" rather than just "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)" // <== tag.name is the key item here
  }
}

let firstPost = Post(title: "Some title", author: "Fred G.", tag: Tag(name: "News"))
let postDescription = firstPost.description()
