Structs

Not sure what I am doing wrong. Thanks.

structs.swift 
struct Post {
    let title: "String"
    let author: "String"
    let tag: Tag

    let Post = "title: \(String), author: \(String), tag: \(tag) { 
}

There are a couple of mistakes in your syntax.

  1. The type is not declared correctly

  2. You have to create the instance outside of the class definition

Also, if you practice everything in the Xcode playground, you will get a much better feel for how things work and it makes debugging much faster and easier.

struct Tag {
    let name: String
}

struct Post {
    let title: String // declare type
    let author: String
    let tag: Tag

}

let firstPost = Post(title: "First Post", author: "Author Name", tag: Tag(name: "tag name")) // Be sure to initialize the tag too

I hope that helps,

Mike
