There are a few things incorrect with your code
struct Tag {
let name: String
}
struct Post {
var title: String
var author: String
var tag: Tag
func description() -> String {
//You do not need to have a constant here, just a return also you need .name added to tag to adhere to the struct
return "\(title) by \(author). Filed under \(tag.name)"
}
}
let firstPost = Post(title: "The Hero", author: "Jeff McDivitt", tag: Tag(name: "One"))
//You have things a little backwards here, just break it down like calling a normal function and I believe you will see the issue
let postDescription = firstPost.description()
Hope this helps!! Happy Coding :)

The main issue is that description() does not take any argument, and also it is not a static function, so it can't be called on the Type itself. but you are calling it with argument on the type: Post.description(firstPost).
