"Implementation of Description" not being accepted as correct, why not?

struct Tag { let name: String }

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

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

let firstPost = Post(title:"iOSDevelopment", author:"Apple",tag:Tag(name:"Swift"))

let postDescription = firstPost.description()

// THERE IS NOTHING TO CHECK IN THE OUTPUT, I'VE NO FEEDBACK. // It mentions to use string interpolation. I am doing so. I also tried the following: // return "(title) by (author). Filed under (tag.name)." //this fails as well.

structs.swift 
struct Tag {
  let name: String
}

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

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

let firstPost = Post(title:"iOSDevelopment", author:"Apple",tag:Tag(name:"Swift"))

let postDescription = firstPost.description()

First, there's no dot at the end of the sentence you are supposed to return.

Second, you have to return that sentence, not a constant/variable. So, not this: let something = "AAAAA" return something But this: return "AAAAA"

Thanks for answering. I figured it out soon after posting but don't know how to retract a post.

The extra "." was the problem. Returning a constant with the string is OK, although I initially started with just returning a string, I changed it when I couldn't figure out what the problem was.
