Having trouble with code challenge struct.swift task 2 of 2. Whats needs to be changed??

The compiler returns a statement saying "Bummer! Make sure the implementation of description matches the directions. Hint: Use string interpolation!"

I know what string interpolation is and I thought that I was using it correctly, what do I need to change in my code?

structs.swift 
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()

Hi Brandon,

In your interpolated string you want to use the name property of the Tag instance. Use dot notation.

Make sense?

Steve.
