No runtime errors however I know that there is a better way of doing this I just can't figure it out.
struct Tag {
let name: String
}
let tagX = Tag(name: "x")
struct Post {
var title: String
var author: String
var tagX: Tag
init(title: String, author: String, tagX: Tag){
self.title = title
self.author = author
self.tagX = tagX
}
}
let firstPost = Post(title: "Apple", author: "IOS", tagX: Tag(name: "APPLE"))

2,998 PointsHi William from the code above it looks like you wanted to solve the second part of the code challenge. Structs issue member wise initializers so you don't need to create one. They ask for a instance method for the Post struct, always think of methods as special functions that exist in a struct or class. In addition they want you to use some string interpolation, the instance method will have no parameters and return a string. When you access a stored property in a struct you use dot notation, this would have to be done for the name stored property in the Tag struct.
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: "iOS Development", author: "Apple", tag: Tag(name: "Swift"))
let postDescription = firstPost.description()
