unable to show only string for tag

"iOS Development by Apple. Filed under Tag(name: "swift")"

Why is 'Tag(name:"swift")" showing?

structs.swift 
struct Tag {
    let name: String
}

struct Post{
    let title: String
    let author: String
    let tag: Tag

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

let firstTag = Tag(name: "swift")

let firstPost: Post = Post(title: "iOS Development", author: "Apple", tag: firstTag)

let postDescription = firstPost.description()

In that method you are using a Tag instance while you should be using its property "name"

In other words, tag does not equal tag.name :)
