iOS Build a Simple iPhone App with Swift 2.0 Getting Started with iOS Development Swift Recap Part 1

Swift Recap Part 1 Task 2 of 2

Add an instance method to Post. Name it description , it takes no parameters and returns a string that describes the post instance. For example, given a title: “iOS Development”, author: “Apple” and a yag named “swift” —> “iOSDevelopment by Apple. Filed by swift”

Once instance method is created, call it on the firstPost instance and assign the result to a constant named postDescption.

structs.swift
struct Tag {
    let name: String
}

let someTag = Tag(name: "swift")

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: "iOS Development", author: "Apple", tag: someTag )

let postDescription = firstPost.description()

You've probably answered this by now but I'm gonna give you the answer anyway incase you haven't

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

let postDescription = firstPost.description()

@EdwardLaurenson I thought that you had to use "()" notation for string interpolation? Why is yours missing a \ in front of the ()? But thanks for the help!
