1,325 PointsWhat is the problem with my code here?
The challenge tells me: "Bummer: Make sure the implementation of description matches the directions. Hint: Use string interpolation!"
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 swift = Tag(name: "swift")
let firstPost = Post(title: "Spike Game", author: "Mathieu Monat", tag: swift)
let postDescription = firstPost.description()

try \(tag.name)
.

54,668 PointsStrange. I tried the following which only has that change and it passed:
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 swift = Tag(name: "swift")
let firstPost = Post(title: "Spike Game", author: "Mathieu Monat", tag: swift)
let postDescription = firstPost.description()
May be a caching issue?
