iOS Swift 2.0 Protocols Creating Flexible Objects Using Protocols Protocol Inheritance

please help :\

Challenge Task 1 of 2

In the editor, I've provided a simple protocol to represent an animal.

For the first task, create a protocol named PetType. PetType should inherit from AnimalType and require an additional gettable stored property, cuddlyName, of type String.

protocol AnimalType {
  var numberOfLegs: Int { get }
protocol PetType = AnimalType {
var cuddlyName: String { get }

You've nearly got it! You need to use a colon instead of an assignment operator between PetType and AnimalType:

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

I hope this helps!

oh.. thank you :smile:
