What steps am I missing? Swift Recap Part 1

When I try my code in a swift playground I get what the challenge is asking for but when I click check work all I get is this: "Make sure the implementation of description matches the directions. Hint: Use string interpolation!"

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 tag1 = Tag(name: "swift")
let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: tag1)
let postDescription = firstPost.description()
