Why this code is not a valid answer?, I already make the description instance method returning a String

after check work it tells me that add a instance method that return a String, but it is already implemented.

Kind regards.

struct Tag {
    let name: String

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

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

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

Hey Rafael.

Your problem is being caused by a space that shouldn't be there. In your function, you have a space between description and the parenthesis. Get rid of that space and you're good to go.

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

And just a note... you don't need to use self in the function. The code will be fine without that.

Keep Coding! :dizzy:
