You copied something from somewhere that, probably har the wrong encoding. Or dunno, i literary retyped your function and it worked. 

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

Hi Ivan, Many Thanks. It appears I spelled description incorrectly on the final line. You spelled correctly!
