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

Confused on the Code Challenge

I don't see what I'm doing wrong when it says "Bummer! Make sure the implementation of description matches the instructions." I can't understand what part of my code is different than what they're describing.

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()

I almost fell for this one too. In your code, "tag" isn't a String, it's a Tag type. The string you are looking for is its "name" property. If you replace "tag" with "tag.name" it should work.

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