Have you encountered a task of transforming the application's interface to support both portrait and landscape device orientations?

To support portrait and landscape orientations in an iOS app, adaptive interfaces with Auto Layout and Size Classes are typically used. In UIViewController, you can override the viewWillTransition(to:with:) method to respond to orientation changes and adjust the layout of elements as needed.

Using Auto Layout with NSLayoutConstraint allows the UI to automatically adapt to orientation changes without manual code.

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)
    coordinator.animate(alongsideTransition: { _ in
        // Update layout or hide/show elements
    })
}

You can also use Size Classes in Interface Builder to configure different interface layouts for Compact and Regular width/height, which is convenient for different orientations.
