Pass keyword in Swift

I know that the "pass" keyword in Python will leave a line of code empty where it should contain an executable statement. Is there a similar keyword in Swift?

I am using a switch statement and Swift requires this to be the default case. The code should get to the default instructions in most cases, and I don't want anything to be done in this case.

You can get out of the default case. Swift just wants you to be honest about this to avoid mistakes.

Here's a simple example:



enum Food {
    case Banana
    case Apple
    case ChocolateBar
}

func warnIfUnhealthy(food : Food) {
    switch food {
    case .ChocolateBar:
        println("Don't eat it!")

    default:
        break
    }

}

let candy = Food.ChocolateBar

warnIfUnhealthy(candy)

The correct way to add catch-all without action to a switch statement is to add

default: break


at the end.
