I'm having trouble with code challenge structs.swift task 2 of 2 within the "creating a simple iPhone app" course.

There are no errors with the code but results say I need to use string interpolation with the description method( which is defined in the instructions), but I thought I already did that in my code. What do I need to change???

structs.swift 
struct Tag {
  let name: String
}

struct Post {

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

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

} 

let firstPost = Post(title: "iOS Developement", author: "Apple", tag: Tag(name:"swift"))

let postDescription = firstPost.description()

It specifically says "Bummer! Make sure the implementation of description matches the directions. Hint: Use string interpolation!"

You have author in there twice in your method, one should be title

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

It just passed for me as 

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)"
}

} 

let firstPost = Post(title: "iOS Developement", author: "Apple", tag: Tag(name:"swift"))

let postDescription = firstPost.description()
