Calling an embedded function on an instance of a struct

How would you call the function description on the instance firstPost after firstPost has been created and then assign it to postDescription? Thanks!

structs.swift 
struct Tag {
    let name: String
}
struct Post {
    var title: String
    var author: String
    let tag: Tag

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

let firstPost = Post(title: "Get wins", author: "Arius Eich", tag: Tag(name: "Arius"))




let postDescription = firstPost

To call the function description on firstPost you need to do firstPost.description() so you will have

let postDescription = firstPost.description()
