iOS Build a Simple iPhone App with Swift 2.0 Getting Started with iOS Development Swift Recap Part 1

Issue with task 2 of "Swift Recap 1" code challenge in "Build a Simple iPhone App with Swift 2.0"

I think the code challenge processor is broken. Here's a link to the code challenge:

https://teamtreehouse.com/library/build-a-simple-iphone-app-with-swift-20/getting-started-with-ios-development/swift-recap-part-1

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.name)"
    }
}

let firstPost = Post(title: "Expert Business Analysis", author: "Audu", tag: Tag(name: "Genius"))
let postDescription = firstPost.description()

I just ran it again and it stopped working but this is the code that worked:

struct Tag {
    let name: String
}

let firstTag = Tag(name: "swift")

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: firstTag)
let postDescription = firstPost.description()

It works in the playground but not in the challenge

Thanks ever so much Angel. The same thing happened to me. It worked in the playground but for some reason doesn't work in the code challenge. I have notified treehouse. Thanks again

In your code is a space between the function name and the (). And the . at the end of the String is too much. With fixing the two things it worked for me

You have to create a tag with the string "swift" and then print the message "iOS Development by Apple. Filed under swift." replace your firstPost with this:

//Tag
let firstTag = Tag(name: "swift")

let firstPost = Post(title: "iOS Development", author: "Apple", tag: firstTag)  

Replaced it exactly as you advised and it's still not giving me joy

Did you add the firstTag constant above the Post struct? I just ran the code and it passed.

it worked it worked it worked. Thanks again for your help

This didn't work for me. Appears to be bugged as it runs in Playground fine.

If it doesn't work you should report it to treehouse sometimes the code challenge environment gets buggy and they will look into it.
