Code works in Xcode, but doesn't work here

What's wrong?

structs.swift 
struct Tag {
    let name: String
}
struct Post {
    let title: String
    let author: String
    let tag: Tag

    init(title: String, author: String, name: String){
        self.title = title
        self.author = author
        self.tag = Tag(name: name)
    }
    func description() -> String {
        return "\(title) by \(author). Filed under \(tag)"
    }
}
let firstPost = Post(title: "iOS Development", author: "Apple", name: "Swift")
let postDescription = firstPost.description()

Hey alexander, there is no need for an init method though, but your code should work if you change it this way.

let firstPost = Post(title: "iOS Development", author: "Apple", name: "Swift")

to

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

This should get you through the 1/2 challenge Task Greetings, Tim

Thanks a lot. It was very helpful.

But your code gives me String: "iOS Development by Apple. Filed under Tag(name: "swift")" So I also changed func description to solve challenge

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