confused

I'm totally confused, shall I create a function inside the structure Post and why??

structs.swift 
struct Tag {
    let name: String = "Book"
}
struct Post {
    let title: String
    let author: String
    let tag: Tag

}
let firstPost = Post(title: "Laurence of Arab", author: "Haitham Alam", tag: Book)

Hey,

by just using "Book" as tag, the complier doesn't know that you refer to the "Tag" struct. I solved it, by creating an instance of Tag:

struct Tag { let name: String }

let firstPost = Post(title: "Laurence of Arab" , author: "Haitham Alam" , tag: Tag("Book"))

Edit:

Here another approach, which I prefer the most:

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

let bookTag = Tag(name: "Book")

let firstPost = Post(title: "Laurence of Arab", author: "Haitham Alam", tag: bookTag)

This way you define your tags once and make them more usable within your code. This also prevents typos (and accidentally setting a new tag instead of using an existing one).
