2,225 PointsMy code runs in Xcode but Tree House keeps telling me that I have an error
//Why does Treehouse keep saying I have an error? 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: "Hello", author: "World", name: "Brice") let postDescription = firstPost.description()
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: "Hello", author: "World", name: "Brice")
let postDescription = firstPost.description()

71,830 PointsThe 3rd parameter when creating a Post is a Tag object, not a String.
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String {
return "\(title) by \(author). Filed under \(tag.name)"
}
}
let tag = Tag(name: "swift")
let firstPost = Post(title: "iOS Development", author: "Apple", tag: tag)
let postDescription = firstPost.description()
P.S., as you can see, you don't need the init you wrote. The default member wise initializer will do the same thing.
