Is it possible to implement a custom window class inheriting from the standard UIWindow?

Yes, it is possible to create a custom class inheriting from the standard UIWindow in iOS. This allows you to extend or modify the window's behavior, such as adding custom event handling or changing its appearance.

Example of simple inheritance:

class CustomWindow: UIWindow {
    override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
        // Custom touch handling logic
        return super.hitTest(point, with: event)
    }
}

However, it is important to remember that UIWindow is a fundamental class for displaying the interface, and excessive modifications can lead to unpredictable behavior. Therefore, inheritance is justified if there is a specific task that cannot be solved in another way.
