I am really confused as to how to use the Tag struct in the post Struct

How can I use my tag struct in the firstPost instance?

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.name){
    self.title = title
    self.author = author
    self.tag = tag
  }
}

let firstPost: Post = Post.init(title: "Hello", author: "Me", tag.name= "Me")

Hi Mohamed Almulla,

You are pretty close actually (nice work!).
The init function isn't required and you'll need to create/instantiate a new tag when creating the firstPost Post :smile:

So try ditching the init func and changing your firstPost to something like:

let firstPost = Post.init(title: "Hello", author: "Me", tag: Tag(name: "Me"))
// You *could* create a new tag before the firstPost then just pass that through as it's of Type tag, but why not just do it inline  

Should be cooking with gas after that! Happy coding.
