return "\(self.title) by \(self.author). Filed under \(bookTag)" not sure why this is not working

I tried it with self.bookTag also.

structs.swift 
struct Tag {
    let name: String
}

struct Post {
  let title: String
  let author: String
  let tag: Tag

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

let bookTag = Tag(name: "swift")

let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: bookTag)

let postDescription = firstPost.description()

Hey there! Almost there, I just added my comments to the code below.

struct Post {
  let title: String
  let author: String
  let tag: Tag

  func description() -> String {
    // Your code:
    // return "\(self.title) by \(self.author). Filed under \(bookTag)"
    //
    // Just a minor thing, but you do not need self here, as it is unambiguous.
    // Moreover, bookTag is not a stored property of this struct, but tag is.
    // Additionally, tag is a struct. If you want to access the name, you have to
    // use dot notation. The following should work:
    return "\(title) by \(author). Filed under \(tag.name)"
  }
}

Hope that helps :)
