Navigating View Controllers in Swift: Best Practices and Methods


In Swift, there are several ways to transition to the next view controller. Here are the commonly used methods:
  1. Segue:
    performSegue(withIdentifier: "NextViewControllerSegue", sender: self)
  2. Storyboard ID:
    // Instantiate the next view controller with identifier "NextViewController"
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let nextViewController = storyboard.instantiateViewController(withIdentifier: "NextViewController")

    // Present the view controller
    present(nextViewController, animated: true, completion: nil)
    // or
    navigationController?.pushViewController(nextViewController, animated: true)
  3. Completion Handler or Delegate:
    // Define a completion handler or delegate protocol in NextViewController

    // Instantiate the next view controller and set the completion handler or delegate
    let nextViewController = NextViewController()
    nextViewController.completionHandler = { result in
     // Handle the completion and transition back if needed
    }
    // Present the view controller
    present(nextViewController, animated: true, completion: nil)
    // or
    navigationController?.pushViewController(nextViewController, animated: true)
Remember to replace "NextViewController" with the actual name of your next view controller class and make sure you have the correct identifiers set up in Interface Builder or storyboard file.
