iOS Intermediate Swift 2 Extensions and Protocols Protocol Conformance Through Extensions

In the editor you have a protocol, PrettyPrintable along with a struct, User.

please help :\

In the editor you have a protocol, PrettyPrintable along with a struct, User.

Your task is to extend User to conform to PrettyPrintable by adding a computed property that returns a formatted description of a User instance.

Arthur, you need something along these lines:

// Enter your code below
extension User: PrettyPrintable {
    var prettyDescription:String {
        return ""
    }
}

Use the keyword extension. Add the protocol that user will conform with after the :. Then add the computed property. As the challenge says, what you return doesn't matter, as long as it's a String.
