"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"
Not sure why it's failing? I placed it on xCode and it seems to work there.
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
init (title: String, author: String, tag: String) {
self.title = title
self.author = author
self.tag = Tag(name: tag)
}
func description() -> String{
return "\(title) by \(author). Filed under \(tag.name)"
}
}
let firstPost = Post(title: "iOS Development", author: "Apple", tag: "Swift")
let postDecription = firstPost.description()

struct Post { let title: String let author: String let tag: Tag
func description() -> String{ return "(title) by (author). Filed under (tag.name)" } }
let firstPost = Post(title: "Treehouse blog", author: "S. Hunter", tag: Tag(name: "Swift, iOS")) let postDescription = firstPost.description()
the problem with your answer is that your tag Tag you didn't add the Tag(name: "Swift, iOS")) part which in playground it won't automatically do it for you so you have to remember that when using tag type.

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 firstPost = Post(title: "iOS Development", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()
