How does changing the frame boundaries in the viewDidLayoutSubviews method affect the interface display?

The viewDidLayoutSubviews method is called after the system has calculated and set the sizes and positions of all subviews in the hierarchy. Changing the frame property within viewDidLayoutSubviews allows for dynamically adjusting the size and position of views after automatic layout.

If you change the frame in this method, the interface will update with the new sizes and positions, which is useful for adaptive design or when changing the screen orientation. However, it is important to avoid infinite loops, for example, if changing the frame causes viewDidLayoutSubviews to be called repeatedly.

Example:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    myView.frame = CGRect(x: 10, y: 10, width: view.bounds.width - 20, height: 100)
}

Here, myView will be stretched across the width with 10-point margins after each layout.
