Can someone please tell me what's going on?
struct Tag {
let name: String
}
struct Post {
var title: String
var author: String
var 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)"
}
}
let firstPost = Post(title: "iOS Development", author: "Apple", name: "swift")
let postDescription = firstPost.description()

Martin Wildfeuer
Courses Plus Student 11,071 PointsThere is one tiny thing in the description: replace tag
with tag.name
so it will not output the Tag
struct, but the name
property of Tag
.
return "\(title) by \(author). Filed under \(tag.name)"
Although your code works perfectly, code check expects the tag being passed to the initializer, instead of it being created in a custom initializer. By doing that, you can get rid of your custom initializer and use the default one created for you.
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)"
}
}
// Pass a Tag instance rather than a string
let firstPost = Post(title: "iOSDevelopment", author: "Apple", tag: Tag(name: "swift"))
let postDescription = firstPost.description()
I have to say that this is not obvious, even more so your code triggers a compiler error in code check but no output.
The reason is that code check tries to test your initializer by passing a Tag where you are expecting a string name
instead.
Hope that helps :)

Courses Plus Student 8,159 PointsIt makes sense but it is still not working...just posted another question.
