What is the default or accepted convention for swipe gestures on mobile application

It seem like some applications provide clear labels, icons and call-to-actions that indicate the outcome of swiping gestures while other mobile applications seem to assume a convention or informs the user after they discover the function/feature.

Is there a consensus on whether swiping left or right implies a primary or secondary action? Should it reflect the Okay/Cancel pattern for buttons or be different because the context or convention for gesture interactions is different?
