iOS Protocols in Swift Creating Flexible Objects Using Protocols Protocol Inheritance

Protocol Inheritance Challenge Task 1: The error is that I need to add a method. The instructions don't mention methods.

The error says that I need to add a method. However, the instructions mention two properties but no method.

protocols.swift

  var numberOfLegs: Int { get }
}

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

Hi erin,

Similar to how the Animal protocol only has a getter, you only want a getter for Pet (which inherits from Animal), as well.

protocol Animal {
  var numberOfLegs: Int { get }
}

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

Hope this helps!
