It appears that the UIPopoverPresentationControllerDelegate protocol includes the UIAdaptivePresentationControllerDelegate protocol, which has 

    // Called on the delegate when the user has taken action to dismiss the presentation successfully, after all animations are finished.
    // This is not called if the presentation is dismissed programatically.
    @available(iOS 13.0, *)
    optional func presentationControllerDidDismiss(_ presentationController: UIPresentationController)

and presentationControllerDidDismiss() appears to be called when the popover is dismissed.

Sadly, Apple's documentation leaves no hint. I would solve things this way.

You setup the popover and obtain the UIPopoverPresentationController like so:

UIViewController* controller = [[MyCustomViewController alloc] init];
controller.modalPresentationStyle = UIModalPresentationPopover;

[self presentViewController:controller animated:YES completion:nil];

UIPopoverPresentationController* pc = [controller popoverPresentationController];
pc.sourceView = self.view;
pc.sourceRect = CGRectZero;

The controller object here represents the main view controller wrapped by the popover—your custom view controller. I think your best bet is to override the -viewDidDisappear: method of your custom view controller. That method will be called when the popover presentation controller dismisses the popover. 

- (void)viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
    NSLog(@"%@ - %@", NSStringFromSelector(_cmd), self);
    // Do the needful.
}

I think it is a shame on Apple that they provided no rationale for the deprecation or suggestions as to how to handle it. Hope that helps!
