Hey! the error says: "Make sure you extend User and conform to PrettyPrintable"
What am I Doing Wrong! Typo?
protocol PrettyPrintable {
var prettyDescription: String { get }
}
struct User: PrettyPrintable {
let name: String
let ID: Int
var prettyDescription: String {
return "User name is \(name) and UserID is \(ID)"
}
}
// Enter your code below

you were on the right track but in this case you want to add additional functionality to the existing User struct by using an extension like you saw in the video before.
To do this you can use the extension keyword in combination with the struct you want to add the functionality to followed by the protocol you want to conform to:
protocol PrettyPrintable {
var prettyDescription: String { get }
}
struct User {
let name: String
let ID: Int
}
// Enter your code below
extension User: PrettyPrintable {
var prettyDescription: String {
return "Name: \(name), ID: \(ID)"
}
}
I hope that helps, good luck! :)
