In Swift 3.0

It creates the standard defaults file and configures it if it does not exist, or open it if it does.

if !defaults.standard.bool(forKey: "onoroff") {
            defaults.standard.set(true, forKey: "onoroff")
     } else {
            defaults.standard.set(false, forKey: "onoroff")
     }
