Calling Functions

What would be the proper way here to return the string value. It currently returns "iOSDevelopment by Apple. Filed under Tag(name: "swift")"

I've tried creating an instance for Tag and assigning it to a constant and using that constant as the value for tag. And still had no luck.

Can't seem to figure this one out. Any help?

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: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift"))

let postDescription = firstPost.description()

If I understand correctly, you are getting 

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

and would like to see 

iOS Development by Apple. Filed under swift

instead. If so, try this for the function:

    func description() -> String {
        return "\(title) by \(author). Filed under \(tag.name)"
    }
