what am i doing wrong here?

Bummer! 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 someTag = Tag(name: "Jake")  
let firstPost = Post(title: "Yeah", author: "Yup", tag: someTag)
let postDescription = firstPost.description()

The problem is the Tag, the tag constant by itself refers to the tag instance, to access the name property of the tag you have to use tag.name.

So your interpolated string should look like this:

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