Bummer! Make sure User specifies a gettable property named `name` of type String

what is happening here

Hey Josh, I think this is a challenge only thing as Playground seems to recognise your code but you can't have a space before the colon for this challenge, try:

protocol User {
    var name: String { get }
    var age: Int { get set }
}
