The tag part isn't quite right. It is of type Tag, not a String. The rest is looking pretty good with some adjustments for that. Try this:
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()
So, the Tag is created in the constructor for the Post struct. Your solution is interesting; I think the compiler is looking for something precise, though. I like your method but the tests in the challenge will be expecting to pass a Tag object into the Post struct, not a String.
Make sense?
Steve.
