Implementation not matching the description??

Please help me, where am I off. I cannot see where it doesn't match the description

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: "iOS development", author: "Apple", tag: Tag(name: "swift"))
firstPost.description()
let postDescription=firstPost.description()

You need to use a dot notation to access the name property on the Tag instance and you don't need this line of code (firstPost.description())

Here's how it should be:

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 firstPost = Post(title: "Challenge Answer", author: "MADadalt", tag: Tag(name: "Community"))

let postDescription = firstPost.description()
