What I'm doing wrong in this?

Kindly let me know what I am doing wrong in this code

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:"Aman", author: "Singh", tag: Tag(name: "deep"))
//let secondPost = Post(title:"Aman", author: "Singh", tag: Tag(name: "deep"))

let postDescription = firstPost.description()

Hey there singhaman,

The problem is with how you're accessing the value for the name property of Tag inside the return of your instance method. You need to access the name property of your Tag instance using dot syntax.

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)" // use tag.name
  }
}

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

Good Luck!
