Not understanding the use of the Tag Struct in quiz question

I'm getting an error on this "quiz" because I don't understand what I'm supposed to put for an argument below where I've added question marks (for this post, not in my submission).

Any pointers are appreciated.

struct Tag { let name: String } let name = "novel" struct Post { var title: String var author: String var tag: Tag } let firstPost = Post(title: "Book", author: "Bill", tag: ???????)

structs.swift 
struct Tag {
    let name: String
}
let name = "novel"
struct Post {
    var title: String
    var author: String
    var tag: Tag
}
let firstPost = Post(title: "Book", author: "Bill", tag: name)

The tricky thing is that the tag property of your firstPost instance of the Post struct also needs to be initialized. You can do it right at the same time all in one line:

struct Tag {
    let name: String
}

struct Post {
    var title: String
    var author: String
    var tag: Tag
}

let firstPost = Post(title: "Book", author: "Bill", tag: Tag(name: "novel"))

(I got rid of your name constant because it had the same name as the parameter name in the constructor and I didn't know how to handle that.)
