Once you have an instance method, call it on the firstPost instance and assign the result to a constant ...

I don't know what i must do in the step 2

structs.swift
struct Tag {
  let name: String
}

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

  func description() -> String {

  }
}

let firstPost = Post(title:"H", author: "H", tag: Tag(name: "H"))

You need to return a string interpolation, using the example provided and then create a constant calling the description method using the firstPost instance. Like so:

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: "H", author: "H", tag: Tag(name: "H"))
let postDescription = firstPost.description()

Community has most of the answers to these challenges. Always search the community for the answer before opening a thread. There a lot of people with the same doubts as you out there. It helps a lot to check out what other people are having trouble with. I know I started to get the basics much better after I started cruising around here.

Also reading the instructions very closely, copying all course codes, checking the Swift guidelines and reviewing the videos are a great way to try solving your doubts by yourself.

Hope I could help! Community is the best place to look for answers.
