Now we're going to focus on Switches for
a minute and

see what we can learn by revisiting
Apple's documentation on UI controls.

When we use buttons,

we configure our target actions to
work with the event touch up inside.

What's the name of the event
that corresponds with the switch

being thrown?

How do we know if the switch is on or
off?

Find the class reference document for
UI switch and

then check the correct options.
