Modify the isGreater function to only accept one parameter. Keep the newValue parameter and remove the currentValue para

Modify the isGreater function to only accept one parameter. Keep the newValue parameter and remove the currentValue parameter because you can retrieve the existing value using the keyword self.

enum.swift
enum Coin: Int {
    case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25 

    func isGreater(currentValue: Coin, newValue: Coin) -> Bool {
        return currentValue.rawValue > newValue.rawValue
    }
}

Just replace currentValue with self:

enum Coin: Int {
    case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25 

    func isGreater(newValue: Coin) -> Bool {
        return self.rawValue > newValue.rawValue
    }
}
