10,756 PointsCant finish chalenge of Swift Recap
My code works in PlayGround . When I try to run it in the course I get this error and coment : "Make sure you create an method called description that returns a String" . I have a func called description and it returns a String... What am I doing wrong?
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
init (title: String, author: String, name: String) {
self.title = title
self.author = author
self.tag = Tag(name: name)
}
func description () -> String {
return "\(title) by \(author). Filed under \(tag.name)"
}
}
let firstPost = Post(title: "iOSDevelopment", author: "Apple", name: "swift")
let postDescription = firstPost.description()

10,756 PointsThank you Michael,
This solved my problem. Also you are right, I did not need to create a init method. It is always better to keep it simple...
Thanks again for taking the time to answer me,
Normand

10,101 PointsHi there,
I think the problem is that you have a typo in the course name.
let firstPost = Post(title: "iOSDevelopment", author: "Apple", name: "swift")
// You are missing a space in "iOS Development"
let firstPost = Post(title: "iOS Development", author: "Apple", name: "swift")
Also, you do not need to create any init when you create a struct since a struct comes with a default initializer. The code below is all that is really needed.
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()
I hope that helps,
Mike
