Confused

Can someone please walk me through this a bit? I dont understand...

structs.swift 
struct Tag {
    let name: String
}

struct Post {

let title: String
let author: String
let tag: Tag
let description: String = Post()

}
let firstPost = Post.description(title: "Some Title", author: "Some Author", tag: Tag(name: "Some Name"))

First, you don't need a constant for description, because you will compute it.

Second, you need to create a method (fund description() -> String) to compute and return the description.

Third, to get the Editor to accept it you need to use the exact text it gives you for the arguments when you are creating the Post object to assign to firstPost.

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()

Happy coding!!

Thanks for the help, it worked perfectly. But that isn't what the instructions said... why is it so hard to understand the instructions? Ugh!
