String Interpolation

I am trying to submit my code for this code challenge but the error says my string implementation is not correct and I should use string interpolation. I am not sure why it is giving me this error because everything seems to be correct

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

Tag is a struct so when you say \(tag) the compiler is confused. You probably ment the name of the tag so that would be \(tag.name)
