2,898 Pointswhy is the stored property "tag" not assigned properly? Please help me out.
returning "tag" doesn't work. Why?
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description()->String {
return "\(title), \(author), \(tag)"
}
}
let Hashtag = Tag(name:"Denis")
let firstPost = Post( title:"Happy Days",author:"Peter", tag: Hashtag )
let postDescription = Post.description(firstPost)

57,712 PointsHi Ken,
You want to output the name
property of the Tag
instance which is called tag
. Chain name
onto your tag
using dot notation.
Also, description
takes no parameters and should be called on the instance of Post
which is called firstPost
. Again, use dot notation on firstPost
to call .description()
on it - assign the returned string from that into postDescription
.
Lastly, I think your output string needs some work - it needs to match the string in the challenge, i.e. "\(title) by \(author). Filed under \(tag.name)."
Steve.
P.S. you can create the Tag
instance in your call to the Post
init method:
let firstPost = Post(title: "Happy Days", author: "Peter", tag: Tag(name: "Denis"))
