Beginning Protocol Code Challenge #1

Hi,

Why is the Code Challenge not accepting my answer? It gives the error, "Make sure User specifies a gettable property named name of type String", but I thought I did specify a gettable property named 'name'.

Thanks, Chase

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

Hi Chase!

You should just use spaces around the gettable and settable. Like this:

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

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

doesn't pass, why?

In the first challenge we are asked to make make a user protocol, in doing so the following fails:

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

even though it does work in XCODE

This passes the challenge:

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

I think it is too strict, if XCode has no problem with it why should it matter? Also the hints don't point out to the fact that it is a syntax problem.

The Colons after the variables, must be right after 'name' and 'age'. So there is two extra spaces over there.

Example:

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