Why is - return "(title) by (author). Filed under (tag)" - returning "A by B. Filed under Tag(name: "C")"
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: "A", author: "B", tag: Tag(name: "C"))
let postDescription = firstPost.description()

10,101 PointsHi David,
You have a small mistake in your description method. You are returning the tag but what you need to return is the Tag.name
See here
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)" // return tag.name
}
}
let firstPost = Post(title: "iOS Development", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()
I hope that helps,
Mike
PS: Thanks to the awesome resources on Team Treehouse, I launched my first app.
Now you can practice writing Swift code directly on your iPhone. You can try the app by clicking on the link below. :-)
