How to do this question?

How would I convert the book name “Percy Jackson” into “PercyJackson” using this code? What additions do I need to make? Reply ASAP.

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: "Percy Jackson", author: "Rick Riordan", tag: Tag(name: "HJK1874"))
let postDescription = firstPost.description()

Hi,

I was having a similar issue but it seems the challenge has a typo and there isn't a need to remove the whitespace in the title. The actual issue is because you have a struct within another struct and therefore have to make a small adjustment to your Struct Tag:

func description() -> String { return "(title) by (author). Filed under (tag)" }

VS.

func description() -> String { return "(title) by (author). Filed under (tag.name)" }

This seemed to work for me. Happy coding
