@implementation ARSafariViewController

- (UIStatusBarStyle)preferredStatusBarStyle
{
    if (self.isSwipingBack)
    {
        return [self.presentingViewController preferredStatusBarStyle];
    }
    
    return [super preferredStatusBarStyle];
}

- (BOOL)prefersStatusBarHidden
{
    if (self.isSwipingBack)
    {
        return [self.presentingViewController prefersStatusBarHidden];
    }
    
    return [super prefersStatusBarHidden];
}

- (void)viewWillDisappear:(BOOL)animated
{
    self.isSwipingBack = YES;
    
    [self.transitionCoordinator notifyWhenInteractionEndsUsingBlock:^(id<UIViewControllerTransitionCoordinatorContext> context) {
        self.isSwipingBack = NO;
    }];
    
    [super viewWillDisappear:animated];
}

- (void)setIsSwipingBack:(BOOL)isSwipingBack
{
    _isSwipingBack = isSwipingBack;
    [self setNeedsStatusBarAppearanceUpdate];
}

@end

I found this doesn't work if

return [self.presentingViewController preferredStatusBarStyle];

returns UIStatusBarDefault but just returning my desired UIStatusBarStyle worked like a charm.

Thanks for sharing, clever workaround.

Thanks @bartvandendriessche 👍
