This excercise doesnt work properly , when I enter the correct answer I keep getting an error message

I answered with

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

}

I still get error Make sure UserType specifies a gettable property name of type String

Hi Safwat,

The problem is simple you have to leave a space between the : and the word String / Int and don't leave a space between the variable name and the : like this:

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

Hope this helped!

Regards, Jari
