let postDescription

I'm trying to figure out what exactly am I doing wrong with this. It does not seem to be compiling.

structs.swift 
struct Tag {
  let name: String
}

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

  init(title: String, author: String, tag: Tag) {
    self.title = title 
    self.author = author
    self.tag = tag
  }

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

let firstPost = Post(title: "iOSDev", author: "John", tag: Tag(name: "swift"))
let postDescription = firstPost.description()

First, you have a typo in your method name, as you know the naming normally doesn’t matter if consistent throughout the code but in these challenges it does. Also you are not assigning the String value of Tag in you method, you are only assigning the tag property witch is of type Tag and that won’t compile. In other words the return of the method should be return "(title) by (author). Filed under (tag.name)" On a side note, you don’t have to initialize a Struct like you have to do with a Class so that’s 4 lines of code you don’t have to write in this case. Good luck!
