swift. UserDefaults and UISwitch - swift

Question

I'm trying to get UserDefaults to work with a UISwitch, but the switch state is not saving when I force close the app and reopen it.
Update: Got it to work. The switch state will stay in either the "on" or "off" state even when the app is closed.
My code:
let defaults = UserDefaults.standard
#IBAction func switchAction(_ sender: UISwitch) {
defaults.set(true, forKey: "saveTrue")
defaults.set(false, forKey: "saveFalse")
if sender.isOn == false {
sender.setOn(defaults.bool(forKey: "saveFalse"), animated: true)
} else if sender.isOn == true {
sender.setOn(defaults.bool(forKey: "saveTrue"), animated: true)
}
}
ANSWER:;;;
let defaults = UserDefaults.standard
override func viewDidLoad() {
super.viewDidLoad()
if let switchValue = getSwitchValue(), switchValue {
switchOutlet.setOn(true, animated: true)
} else {
switchOutlet.setOn(false, animated: true)
}
}
#IBAction func Switch(_ sender: UISwitch) {
if sender.isOn == false {
setSwitchStatus(status: false)
sender.setOn(false, animated: true)
} else if sender.isOn == true {
setSwitchStatus(status: true)
sender.setOn(true, animated: true)
}
}
func setSwitchStatus(status: Bool?) {
if status != nil {
defaults.set(status, forKey: "save1")
}
}
func getSwitchValue() -> Bool? {
return defaults.bool(forKey: "save1")
}

I'm not sure this is what you're looking for but I'd do it like this:
let defaults = UserDefaults.standard
#IBOutlet mySwitch: UISwitch!
//or any other function that is called 'when the app is reopened'
override func viewDidAppear() {
self.mySwitch.setOn(defaults.bool(forKey: "switchDefaultsKey"), animated: true)
}
#IBAction func switchAction(_ sender: UISwitch) {
defaults.set(sender.isOn, forKey: "switchDefaultsKey")
}
