iOS Swift 2.0 Protocols Creating Flexible Objects Using Protocols Protocol Inheritance

I get an error that PetType isn't inheriting AnimalType but I think it is.

Not sure what is wrong, I feel that I have the correct answer.

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

protocol PetType : AnimalType {
  var cuddlyName: String { get }
}

I figured out the error, the TeamTreehouse compiler doesn't like the colon with a space "PetType : AnimalType" and prefers "PetType: AnimalType"

The compiler is having issues, the task gets accepted but when I click to move on it will reset and not record that it has been completed. This happened to me previously in this same block of "Swift 2.0 Protocols". Who do we notify about this?
