Swift Recap Part 1 (Build a Simple iPhone App Course)

I've been stumped on this challenge, since the error I'm getting has no explanation (It just says "Bummer," and there is nothing in the preview tab).

I also tried adding an init method to try and fix it, but nothing worked.

I would appreciate any help. Thanks!

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: "Book", author: "Writer", name: Tag(name: "Swift"))
let postDescription = firstPost.description

Hi Jack -

The task's treehouse are very picky, your code will work, but look at my method you need to use tag.name

struct Tag {
    let name: String
}

struct Post {

    var title: String
    var author: String
    var tag: Tag

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

    }
}

let firstPost = Post(title: "The Task", author: "Me", tag: Tag(name: "Swift"))
let postDescription = firstPost.description()

Thanks a bunch! Didn't realize you needed to use dot notation for the method.

No problem, it is because of the way the structure is set -up that you need to use the dot notation

I literally got stuck on this challenge for an hour bec I had a period after \(tag.name). Very picky.
