Help With a code Challenge

Hi! I've been following the swift course but ended up getting stumped on this one. I am not sure what to supply to the self.tag. I know it needs to be an instance of the Tag Struct but I am not sure how to write that. The Code is

 struct Tag {
  let name: String
}



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



  init(title: String , author: String , tag : String){

  self.title = title 
  self.author = author
  self.tag = 
  }


}

let firstPost = Post(title : "Lord of the Rings" , author : "JRR" , tag : "Magic")  ```

Hi,

Make sure you look through your code before compiling it. For example: the post struct has a tag value of type Tag, while you specify it of type String in the initializer.

Here is the solution:

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
  }

}

let magicTag = Tag(name: "Magic")
let firstPost = Post(title : "Lord of the Rings" , author : "JRR" , tag : magicTag)
