Try this:

@IBAction func soundSwitchs(_ sender: Any) 
{
    UserDefaults.standard.set(soundSwitchOutlet.isOn, forKey: "sound")
    UserDefaults.standard.synchronize() 
}

  //this is inside viewDidLoad and "boolValue" was declared outside viewDidLoad//

 boolValue = UserDefaults.standard.bool(forKey: "sound")
