How do I build a tvOS app with focus engine?

Building a tvOS app with the focus engine involves understanding how to manage focusable elements and how to handle focus updates effectively. In tvOS, focus is the primary means through which users navigate your app, so implementing a smooth and intuitive focus experience is crucial.

Here's an example of how to set up focusable elements in a simple tvOS app:

// Example of a simple tvOS focusable view import UIKit class FocusableViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Create a label as a focusable element let focusableLabel = UILabel() focusableLabel.text = "Focusable Label" focusableLabel.textAlignment = .center focusableLabel.isUserInteractionEnabled = true // Set the label's frame focusableLabel.frame = CGRect(x: 50, y: 200, width: 200, height: 50) focusableLabel.backgroundColor = UIColor.cyan // Add the label to the view view.addSubview(focusableLabel) } // Handle focus update override func didUpdateFocus(in coordinator: UIFocusAnimationCoordinator) { super.didUpdateFocus(in: coordinator) // Implement additional focus logic } }
