I don't understand. Swift is not giving error but getting an error in Treehouse Simulator.

struct Tag { let name: String }

struct Post { let title: String let author: String let tag: Tag

init(title: String, author: String, tag: String) {
    self.title = title
    self.author = author
    self.tag = Tag(name: tag)


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


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