Code doesn't work. Reads well in Playground. Don't understand why it doesn't run in treehouse editor.

Why doesn't my code work even though it works fine in Swift Playgrounds.

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). File under \(tag.name)"
    }

}

let firstPost = Post(title: "iOS Development", author: "Apple", tag: Tag(name: "swift"))

let postDescription = firstPost.description()

Check your description functions return string. Should read "iOSDevelopment by Apple. Filed under swift. Yours says File instead of Filed and sometimes the treehouse editor is looking for an exact string. Hope that helps!
