I don't know where is the problem

they asked the following : But I don't know what to do exactly... Challenge Task 1 of 2

In the editor you've been provided with a Tag type. Create a struct named Post with three stored properties: title of type String author of type String tag of type Tag

Create an instance of Post and assign it to a constant named firstPost.

struct Tag {
  let name: String

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

let firstPost: Post

You got this! You've got the right idea.

You want to assign an instance of Post into firstPost. For that you need an equals sign after let firstPost. Then, you need to pass in some values for each of the three stored properties you've added to the struct. So, pass a String for both title and author and a Tag for tag.

This looks like:

let firstPost = Post(// stored properties in here)

The stored properties are:

title: "a string", author: "a string", tag: ...

I paused. At this point, you want to create a new Tag instance. A Tag is formed with a String called name. So this will create a new Tag:

Tag(name: "aTag")

Add that to the other stored properties above and you get:

title: "a string", author: "a string", tag: Tag(name: "aTag")

Chuck that at the rest of the code and you get

let firstPost = Post(title: "a string", author: "a string", tag: Tag(name: "aTag"))

I hope that makes sense! Shout me if it doesn't!
