Answer 1

Often it is more important to do that from top of stack, so:

- (void)popToLast:(Class)aClass
{
    for (int i=self.navigationController.viewControllers.count-1; i>=0; i--)
    {
        UIViewController *vc = self.navigationController.viewControllers[i];
        if ([vc isKindOfClass:aClass])
        {
            [self.navigationController popToViewController:vc animated:YES];
            break;
        }
    }
}

and you call that

popToLast:[SomeViewController class];

Answer 2

After lots of effort someone has created swift extension of back to a particular view controller in Swift 3.0.

extension UINavigationController {

    func backToViewController(viewController: Swift.AnyClass) {

            for element in viewControllers as Array {
                if element.isKind(of: viewController) {
                    self.popToViewController(element, animated: true)
                break
            }
        }
    }
}

Method calling:

 self.navigationController?.backToViewController(viewController: YourViewController.self)
