Help With Code Challenge. My Code is flawless... I think.

This is my task: Add an init method to the enum Coin and within it initialize the value to a Quarter.

Here is my code: 

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

    init() {
      self = Quarter 
    }

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

This is for the course: Enums and Their Methods.

For some reason I am getting this error message: Add an init method to the enum Coin and within it initialize the value to a Quarter.

Any help would be appreciated.

Thanks.

Almost there, you're missing a .

Try;

 self = .Quarter

To add to why Ben's answer is right, you access enum values using the dot notation like any swift property: Coin.Quarter. Omitting the Coin portion and just using .Quarter is a convenience accessor since Swift knows you're referring to the Coin enum here.
