How to Navigate from one View Controller to another using Swift

Question

I'd like to navigate from one view controller to another. How can I convert the following Objective-C code into Swift?

UIViewController *viewController = [[self storyboard] instantiateViewControllerWithIdentifier:@"Identifier"]; UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:viewController]; [self.navigationController pushViewController:navi animated:YES]; 

Answer 1

Create a swift file (SecondViewController.swift) for the second view controller and in the appropriate function type this:

let secondViewController = self.storyboard.instantiateViewControllerWithIdentifier("SecondViewController") as SecondViewController self.navigationController.pushViewController(secondViewController, animated: true)

Swift 2+

let mapViewControllerObj = self.storyboard?.instantiateViewControllerWithIdentifier("MapViewControllerIdentifier") as? MapViewController self.navigationController?.pushViewController(mapViewControllerObj!, animated: true)

Swift 4

let vc = UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "IKDetailVC") as? IKDetailVC self.navigationController?.pushViewController(vc!, animated: true)
