I am trying to leran how to use UserDefaults with Swift. I need to save the state of a bool statement.

I have a UISwitch that if it is on, the bool statement is true. If it is off, it is false. Like this:

I declare a gloabal variable...

var switchBool : Bool = false

Then I set up the action for the switch... 

 @IBAction func boolSwitchAction(_ sender: Any) {
        if darkModeSwitch.isOn {
            switchBool = true
        } else {
            switchBool = false
        }  
    }

It works great. But then, once the app is shut down, the app does not remember that the switch is on, nor if the switchBool is true. That's why I need to use UserDeafaults. I've looked for some tutorials, but I couldn't find one that would help me. Can someone help me with this? Thanks!
