Hi Andrey,

You are super close.

  1. Return the tag.name in the description method
  2. Remove the empty space in the string that you return at the end

Should look like this.

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.name)" // return the tag name and remove space
    }
}

let firstPost = Post(title: "hello", author: "Andrey", tag:Tag(name: "ready"))
let postDescription = firstPost.description()

I hope that helps,

Mike

your error is in the func description:

you should reference the property in the tag not the object. so change tag to tag.name

cheers!
