How to link a boolean value to the on/off state of a UISwitch?

Question

I have a UISwitch that I want to control a boolean value in a function I wrote. I looked in the UISwitch Type Reference and it listed the property

Answer 1

No need for extra boolean.
use this :

} else {
  // do something else
}

this is an always up to date boolean for switch state, so NO NEED to create your own variable.
