Can anyone explain why this doesn't work? :(

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

Hey man I just had this, don't forget to specify WHICH property of Post you're trying to access using DOT NOTATION!

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")) firstPost.description() let postDescription = firstPost.description()
