How to solve this code challenge?

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. Note: The specifics of the formatted description don't matter to pass this challenge.

protocols.swift 
protocol PrettyPrintable {
    var prettyDescription: String { get }
}

struct User {
    let name: String
    let ID: Int
}

// Enter your code below
