I am stuck. Questions on usage of Tag. Where does the "filed under' come from in for the description?

Im a little bit confused on how to properly use the type: Tag. Furthermore it asked the result to include a 'filed under' string, and I don't know where that is supposed to come from either.

structs.swift
struct Tag {
    let name: String
}

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

    func description() -> String {
        let result = self.title; self.author
        return "\(result)"
    }
}

The tag part can be tricky; let me know if you have any questions on the below

struct Tag {
    let name: String
}

struct Post {

    let title: String
    let author: String
    var tag: Tag

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

let firstPost = Post(title: "Treehouse Blog", author: "S. Thompson", tag: Tag(name: "Swift IOS"))

let postDescription = firstPost.description()
