Swift Recap Part 1 - Objective 2

I cannot get my code through the Code Challenge compiler for the 2nd task. Keeps saying Bummer. No errors in Previewer. My code compiled for Objective 1 and works in the Playground. But will not pass for Objective 2.

Does anyone see an error? I checked for spelling errors and brackets. For Task 2, I just added a method, and called tag.name for the name.

structs.swift 
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: "IOS Development", author: "Apple", name: "Swift")
firstPost.description()
let postDescription = firstPost.description()

Hi Deneen, it might just not like the way you are doing it. A bit too complicated, here is how I did it:

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: "Harry Potter", author: "J.K", tag: Tag(name: "Hello"))

let postDescription = firstPost.description()

Thanks Mitchell.

I made a new initializer because I would not ask a User to enter a structure. And because my code passed the 1st objective, I expected it to pass the 2nd if it didn't have errors and produced the correct result. But, I'll just change it to get the credit and move on.

Hi Mitchell, can you explain this part of the function (tag.name)? why can't I just use (tag) Thanks!

Hi Jenny! If you just put tag, it returns the entire Tag object which is not what we want. We just want the name, which is inside the Tag object. So when we put tag.name, it tells it to just print the name that the Tag object is storing. Does that make sense?
