What am I doing wrong?

I think im doing it right, is it the code checker or am I doing something wrong?

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.name)."
  }

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

Hi, your code is fine. The code checker is just being picky and not giving a particularly helpful error message. If you remove the comma and full stop from your string it will work fine

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