this tag thing is driving me craaaaazy

I just don't get what I'm supposed to be doing with this tag thing.

Please explain?

structs.swift 
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)"

    }
}

let firstPost = Post(title: "Game Of Thrones", author: "George R.R. Martin", tag: Tag(name: "Book"))

let postDescription = firstPost.description()

in your description, you are interpolating the tag struct itself. what you want is its name property specifically. use dot notation to grab the value you are looking for.

return "(title) by (author). Filed under (tag.name)"
