How can I pop specific View Controller in Swift

Question

I used the Objective-C code below to pop a specific ViewController.

for (UIViewController *controller in self.navigationController.viewControllers) {     if ([controller isKindOfClass:[AnOldViewController class]]) {          //Do not forget to import AnOldViewController.h         [self.navigationController popToViewController:controller                                               animated:YES];         break;     } } 

How can I do that in Swift?

Answer 1

Try following code:

for controller in self.navigationController!.viewControllers as Array {     if controller.isKind(of: ViewController.self) {         self.navigationController!.popToViewController(controller, animated: true)         break     } }

Swift 5

To pop to the latest instance of a specific class, for example SomeViewController:

navigationController?.popToViewController(ofClass: SomeViewController.self) 

But you need to add ths UINavigationController extension:

extension UINavigationController {   func popToViewController(ofClass: AnyClass, animated: Bool = true) {     if let vc = viewControllers.last(where: { $0.isKind(of: ofClass) }) {       popToViewController(vc, animated: animated)     }   } }
