Hi Richard,

Your braces for the computed property aren't in the right places.

Here's an example of some code that will work:

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)\n ID: \(ID)"
    }
}
