Hi there! You're so close here! In fact, you're so close I'm going to give you some hints. First, you have an unnecessary line.

This line doesn't do anything, but doesn't cause the failure of the challenge:

firstPost.description()

You can safely remove this line. Now to the root of your problem. The problem is in your description line here:

return "\(title) by \(author). Filed under \(tag)"

Remember that your tag variable is an instance of the Tag struct. But you're not trying to get the entire struct, you're trying to get the name property from that struct. We use dot notation to access the stored properties of a struct. I think you can get it with these hints, but let me know if you're still stuck! :sparkles:

Hey! I had trouble on this challenge too - Thanks Jennifer! :D This is what I got:

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

Hi Elliot, glad to see you resolved your similar issue.

But one suggestion - other readers might enjoy the opportunity to solve the issue from the hints just like you did, so perhaps posting the code spoiler isn't necessary.
