I don't get it... "no accessible initializers"?

Error: Playground execution failed: /var/folders/t7/v5kxmbvn2kbdzkmf59rqlpnh0000gn/T/./lldb/4546/playground24.swift:32:87: error: 'Tag' cannot be constructed because it has no accessible initializers let firstPost = Post(title: "A random title", author: "A random author", tag: Tag(name: "A random tag")) ^

structs.swift
struct Tag {
    let name: String


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

    }
        let firstPost = Post(title: "A random title", author: "A random author", tag: Tag(name: "A random tag"))
}

Ryan, you are close. Just move the Post struct outside the curly braces of the Tag struct. You were getting an error because you cannot have a struct within a struct.

struct Tag {
    let name: String
}

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

let firstPost = Post(title: "A random title", author: "A random author", tag: Tag(name: "A random tag"))

The problem is that you are trying to create firstPost inside the struct. Try this instead:

struct Post {
    let title: String
    let author: String
    let tag: Tag
}    //    end of struct

let firstPost = Post(title: "A random title", author: "A random author", tag: Tag(name: "A random tag"))
