To check if it smart invert is currently enabled you can use UIAccessibility.isInvertColorsEnabled. You can also get a notification when it changes by observing UIAccessibility.invertColorsStatusDidChangeNotification:

NotificationCenter.default.addObserver(forName: UIAccessibility.invertColorsStatusDidChangeNotification,
                                       object: nil,
                                       queue: OperationQueue.main) {
                                        [weak self] _ in
  
  if UIAccessibility.isInvertColorsEnabled {
    // smart invert is enabled
  } else {
   
  }
}
