protocols error

hey guys I think I am doing the write thing but it doesn't work. I tried it on my playground and it ran perfectly

protocols.swift 
protocol Animal {
  var numberOfLegs: Int { get }
}



protocol Pet : Animal{
var cuddlyName: String { get }

struct Dog: Pet {
var numberOfLegs: Int 
var cuddlyName: String 
}
