Slider gesture method not working in iPhone 11

[Razikhan111]

• (void)sliderPanGestureRecognized:(UIGestureRecognizer *)recognizer {
  [self handleSliderGestureRecognizer:recognizer];

  switch (recognizer.state) {
  case UIGestureRecognizerStateBegan:
  if ([self.tapSliderDelegate respondsToSelector:@selector(tapSlider:panBeganWithValue:)]) {
  [self.tapSliderDelegate tapSlider:self panBeganWithValue:self.value];
  }
  break;
  case UIGestureRecognizerStateEnded:
  if ([self.tapSliderDelegate respondsToSelector:@selector(tapSlider:panEndedWithValue:)]) {
  [self.tapSliderDelegate tapSlider:self panEndedWithValue:self.value];
  }
  break;
  default:
  break;
  }
  }

This function in not calling in iPhone 11 when i slide slider.
But this is working fine in iPhone 6.
