Error with compiling

I keep getting an error, but I can't seem to find a solution for my problem.

Thanks for help

structs.swift
struct Tag {
    let name: String
}

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


}

let firstPost = Post(title: "ABC", author: "CBA", tag: //What should I put here??? )

Answer: a Tag. Just as you put a String for title and String for author, because they are declared as Strings, you need to put a Tag for tag. You can do it inline, or you can create a Tag first and then include it. In the code below it's done first:

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

    func description() -> String {
        return "\(title) by \(author). Filed under \(tag.name)"
    }
}

let tag = Tag(name: "swift")
let firstPost = Post(title: "iOS Development", author: "Apple", tag: tag)

let postDescription = firstPost.description()
