5,956 PointsSwift Recap Part 1: can not pass the challenge but works fine in playgrounds
Can anyone please tell me what am I doing wrong here? '''swift 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: "SomeTitle", author: "Some Guy", tag: Tag(name: "TAGTAG")).description()
let postDescription = firstPost
'''
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: "SomeTitle", author: "Some Guy", tag: Tag(name: "TAGTAG")).description()
let postDescription = firstPost

28,558 PointsThere are two issues:
You are calling the
description
method on the line where you create thefirstPost
constant, that causes that constant to be assigned the description string, rather than an instance of thePost
struct like it is supposed to.You have not capitalized the word "Filed" in your string, challenges tend to be very picky about strings so even capitalizing the string wrong will often cause your code to not pass.
If you fix those two issues:
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String {
// Changed filed to Filed
return "\(title) by \(author). Filed under \(tag.name)"
}
}
// Store Post instance in firstPost
let firstPost = Post(title: "SomeTitle", author: "Some Guy", tag: Tag(name: "TAGTAG"))
// Store result of description method in postDescription
let postDescription = firstPost.description()
Then your code will work.
