This code is compiling and executing correctly in Playground but not in this editor. Am I doing something wrong?

I'm getting the correct result for description

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

Hi there,

This isn't working because the challenge is expecting to send two strings and a Tag into the init method, not three Strings.

So at the point where you are creating an instance of Post, create the Tag instance within the call to Post().

Let me know how you get on.

Steve.

Yes, that fixes the problem but the challenge isn't helping you here at all. Your first task shouldn't pass as that's where the error is, but it does. Then the error messages prompts you to hit 'Preview' which shows you nothing as there's no syntax error. That's unhelpful, to say the least!

Thanks Steve! That helped tremendously. I got it.

let firstPost = Post(title: "iOSDev", author: "John", tag: Tag(name: "swift"))
