Converting string

I do not understand why the compiler will not accept a String in a struct of a stored value of tag. Please help

structs.swift 
struct Tag {
  let name: String
}
struct Post {
  var title: String
  var author: String
  var tag: Tag
}

let firstPost = Post(title: "Get wins", author: "Arius Eich", tag: "Morse")

It won't accept a String because the tag property is not defined as a String, but as a Tag. That means that it can only hold instances of the Tag struct, which a String is not.

So you have to create a Tag instance and pass that in, like this:

let firstPost = Post(title: "Get wins", author: "Arius Eich", tag: Tag(name: "Morse"))
