If my code returns a String in a playground why is the editor telling my method needs to return a String?

My method name is correct, and it is return a String. The error is make sure your are declaring a method called description that returns a String. Why would this not be working.

struct Tag {
    let name: String

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

  func description () -> String {

    let result = "\(title) by \(author). Filed under \(tag.name)"
    return result

  let firstPost = Post(title:"Treehouse",author:"Joe Timko",tag: Tag(name:"tag"));
  let postDescription = firstPost.description()

Hey Joseph,

Your code is all correct, except for one spacing issue.

In this line of code,

func description () -> String {

you have a space after 'description' and before the opening/closing parentheses. Swift does not like this. :) Just remove the space...

func description() -> String {

and your code passes with no problems. Keep Coding! :)
