Disha, I used your code in the challenge, and I have found the compilation error. It is only the last line, because there is no need for it in the challenge. The correct code should look like:

struct Tag {
  let name: String
}

struct Post { 
  let title: String 
  let author: String
  let tag: Tag
} 

let firstPost = Post(title: "Treehouse", author: "Pasan", tag : Tag(name: "string"))

If you have any further questions, don't hesitate to ask!

There are two parts to this challenge and I believe she is referring to the second part of the challenge.

Disha,

When I ran your code in Xcode using the playground, I could not get your code to compile because the "\" you are using. I assume you might have been editing your code in Microsoft word or some other text editing software and than pasting it into the challenge?

When I retyped your code in Xcode using the "\" for the following line of code I could get the challenge to pass.

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