iOS Build a Simple iPhone App with Swift Getting Started with iOS Development Swift Recap Part 1

postDescription Problem

Any ideas on this one? I am unsure what's missing.

structs.swift
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()

Hi,

the problem is with your tag.

You see, in your class tag is type of Tag. And Tag is not a String!

But it has string inside called name. So you can use dot notation to get this name and have what you need.

Instead:

tag

you need to use:

tag.name

So this line with description will look like:

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

Fix just that and you are good to go!

Cheers!

BR, Jarek

Of course! That did the trick. Thanks
