iOS Protocols in Swift Creating Flexible Objects Using Protocols Protocol Inheritance

Swift 3 - Pet Protocol Challenge Task 1 of 2: How do I correct method requirement error?

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 Pet which should inherit from Animal and require an additional gettable stored property, cuddlyName, of type String.

I thought what I had was correct, but I keep getting an error telling me to add the required method. Task one does not mention anything about a method.

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

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

I changed let cuddlyName to var cuddlyName and it passed!

protocol Animal {
  var numberOfLegs: Int { get }
}

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

These aren't the codes you're looking for. Move along, move along.
