check if switch is on boolean watchkit

In Swift using iOS I used to be able to do:

if mySwitch.on {

myLabel.text = "The Switch Is In The On Position!"

}else{

myLabel.text = "The Switch Is In The Off Position!"


}

but how do I do if mySwitch.on {} in WatchKit Swift

I saw on apple it told me if mySwitch.setOn(on: Bool) but how do I check to see if 'mySwitch' is in the off or on position.

Does anyone know the correct boolean method?

Thanks,
