Structures

I understood the question and I did the right answer but the error is that to use string interpolation, and I used it.

structs.swift 
struct Tag {
    let name: String
}

struct Post {
    let title: String
    let author: String
    let tag: Tag

    func description() -> String {
      print("\(title) by \(author). Filed under \(tag)")
    }
}

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

Hi Raju,

you are close to the solution. These things need to be changed:

1) the description method should RETURN the description, not print it.

2) in the description method use the name property of tag (tag.name) instead of the instance (tag). The instance itself is not a string.

Good luck
