We learned about instance methods before. For this task, add an instance method to Post.
Name the method description. It takes no parameters and returns a string that describes the post instance. For example given a title: "iOS Development", author: "Apple", and a tag named "swift", the description would read as follows"
"iOSDevelopment by Apple. Filed under swift"
Once you have an instance method, call it on the firstPost instance and assign the result to a constant named postDescription
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)"
}
}
let firstPost = Post(title: "Twinkles Diary", author: "Lana", tag: Tag(name:"hi"))
let postDescription = firstPost.description()

I got stuck with this as well :)
When you return the value you are returning the Tag and what you actually want to return is the value, e.g.
return "\(title) by \(author) filed under \(tag.name)"
if you look at the playground without the name identifier, what you see is Tag(name: "hi")
