Answer 1

@alexander-johmann above has a solution (though I'd like to find another way).

Ideally it would be better to be able to set the actual background color. This solution doesn't really do that; it removes elements of the UIPageControl to get the 'effect' of providing a clear background without actually doing so.

Here is an objective-c version of the same code:

for (UIView *subview in pageControl.subviews) {
    if ([subview isKindOfClass:[UIVisualEffectView class]] == YES) {
        [subview removeFromSuperview];
    }
}

Answer 2

The fix Alexander mentioned didn't work for me when too many pages had to be displayed. I would rather set the effect to nil:

for subview in pageControl.subviews {
    guard let effectView = subview as? UIVisualEffectView else { continue }
    effectView.effect = nil
}

Answer 3

This transparent background is a subview in UIPageControl of type UIVisualEffectView. You could remove it like this:

for subview in pageControl.subviews {
  if subview.isKindOfClass(UIVisualEffectView) {
    subview.removeFromSuperview()
  }
}
