iOS Intermediate Swift 2 Extensions and Protocols Protocol Conformance Through Extensions

This challenge won't let me check my work at all. It basically craps itself as soon as I click the "check work" button.

It's an issue with the website. Already restarted browser and computer.

Gregory, what I've found is that for some of the challenges if you have an error it forces a restart.

Try this, and see if you still have the same problem:

// Enter your code below
extension User: PrettyPrintable {
    var prettyDescription: String {
        return "UserName: \(name), UserID: \(ID)"

let u1 = User(name: "Tom Brown", ID: 14)

Treehouse staff say that restarts are because of browser plug-in conflicts, but I've found that usually not to be the case.
