787 Pointsanybody willing to explain/give code for me. Stuck on enums
enum Coin: Int {
case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25
func isGreater(currentValue: Coin, newValue: Coin) -> Bool {
return currentValue.rawValue > newValue.rawValue
}
}

As per the previous video the challenge is asking that we remove the currentValue
parameter and in place use the self
keyword so we refer to the current enum
rather than accepting it in the method itself.
enum Coin: Int {
case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25
func isGreater(newValue: Coin) -> Bool {
return self.rawValue > newValue.rawValue
}
}
So as you can see currentValue
no longer exists as a parameter in our method and instead of currentValue.rawValue
we now have self.rawValue
which refers to the enum
instance that called the method.
