Why isn't this working? It says cannot convert value of type 'String' to expected argument type 'Tag'

In the editor you've been provided with a Tag type.

Create a struct named Post with three stored properties: title of type String, author of type String, and tag of type Tag.

Then create an instance of Post and assign it to a constant named firstPost.

structs.swift 
struct Tag {
  let name: String

}

struct Post {
  let title: String
  let author: String
  let tag: Tag
}
let firstPost = Post(title: "Hello",author: "Pasan",tag: "Me")

Your "tag" property of your Post struct is looking for an actual Tag struct, not a String. Try this...

let firstPost = Post(title: "Hello", author: "Pasan", tag: Tag(name: "Me"))

You can also create a new Tag object before declaring your firstPost variable...

let myTag = Tag(name: "Me")

then

let firstPost = Post(title: "Hello", author: "Pasan", tag: myTag)
