challenge 1 Protocols doesn't work

why isn´'t it working. The challenge was: Declare a protocol named UserType. The protocol defines two requirements: a gettable property named name of type String, and a gettable/settable property named age of type Int Hint: To declare a property as gettable, add { get } after the type. For settable - { set } and combine both to get a gettable and settable property.

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

It needs to have a space before and after "get" and "set"

Jose is correct. The code should look like this with spaces and all. 

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

Is it normal in XCode, or just special case here to add the spaces?

I believe it's just in here, I tried the code in Xcode without spaces and it worked fine.

I typed this into the challenge and it says "Bummer!" I'm going to try again, but I don't see the problem.

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

}

The problem is with treehouse only, don't worry, just add the spaces between get and the brackets like { get } and { get set } and it will work fine, in xcode it works without the spaces.
