    }
}

Fedor, I was puzzled, because it does work in Xcode, as you indicate. So I re-did the challenge, and got it to work, with the following:

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)"
    }
}

let firstTag = Tag (name: "swift")
let firstPost = Post (title: "iOSDevelopment", author: "Apple", tag: firstTag)
let postDescription = firstPost.description()

You may be puzzled. The only difference is that I don't have a space between description and () in the function declaration!? In fact, once the challenge accepted it, it took me a while to figure out what was different!
