I can't find the error

I guess treehouse dosn't like my code, but I can't figure out why? Can someone help me?

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

The problem is here

return "\(title) by \(author). Filed under \(tag)"

You're returning a "Tag" type and not a "String" type from "tag".
