Hi there,

You create an instance of a struct outside the struct code. So move your line below the closing curly brace, like this. However, you need to pass in values inside the parentheses, (), to fill the title, author and tag properties:

struct Post {
  let title: String
  let author: String
  let tag: Tag
  // let firstPost = Post
}

let firstPost = Post() // <- need properties in here

Good luck!

Steve.
