I don't get these concepts

Please explain in detail the concept of enums with funcs

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
    }
}
