Creating and calling instance methods in Swift 3

What is the correct syntax for creating and calling instance methods in Swift 3? My code is below...currently something is wrong but I'm not sure how to correct it.

struct Tag {
  let name: String
}

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

  func description() {
    "\(title) by \(author). Filed under \(tag)"
  }
}

let firstPost = Post(title: "iOS Development", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()
structs.swift
struct Tag {
  let name: String
}

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

  func description() {
    "\(title) by \(author). Filed under \(tag)"
  }
}

let firstPost = Post(title: "iOS Development", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()

Working solution:

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: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift")) .  
let postDescription = firstPost.description()
