Hey JUNSEI TEI,

Try changing your init method to take a Tag type as a parameter. Then, when creating the post instance, initialize it with a title value of type string, author value of type string, and tag value of type Tag. You can create the Tag instance right inside of the Post initialization.

Also, in the return statement of your instance method, you need to drill down to access the tag properties' name property. You can do this with dot syntax, tag.name.

struct Tag {
    let name: String
}
struct Post {
    let title: String
    let author: String
    let tag: Tag
    init(title: String, author: String, tag: Tag) {
        self.title = title
        self.author = author
        self.tag = tag
    }
    func description() -> String {
        return "\(title) by \(author). Filed under \(tag.name)"
    }
}
let firstPost = Post(title: "TEI", author: "JUNSEI", tag: Tag(name: "TJ"))
let postDescription = firstPost.description()

Good Luck!
