Protocol Inheritance

Hello,

I am having problem with objective 1, I think my code is good, but when I submit it I receive the message: " Make sure you are declaring a protocol named PetType that inherits from AnimalType"

Any ideas?

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

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

1 Answer

Try this! You had two spaces to the left next to AnimalType.

protocol AnimalType {
    var numberOfLegs: Int { get }
}

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

Hope it helps! :D

No problem ;)
