Cant finish chalenge of Swift Recap

My code works in PlayGround . When I try to run it in the course I get this error and coment : "Make sure you create an method called description that returns a String" . I have a func called description and it returns a String... What am I doing wrong?

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.name)"
    }


}
let firstPost = Post(title: "iOSDevelopment", author: "Apple", name: "swift")
let postDescription = firstPost.description()

Thank you Michael,

This solved my problem. Also you are right, I did not need to create a init method. It is always better to keep it simple...

Thanks again for taking the time to answer me,

Normand

Hi there,

I think the problem is that you have a typo in the course name.

let firstPost = Post(title: "iOSDevelopment", author: "Apple", name: "swift")
// You are missing a space in "iOS Development"

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

Also, you do not need to create any init when you create a struct since a struct comes with a default initializer. The code below is all that is really needed.

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()

I hope that helps,

Mike
