Discussion
This method is called when a view controller that doesn’t use Auto Layout has a child view controller that uses Auto Layout and the child view controller is resized. When the child view controller responds to the systemLayoutSizeFitting(_:) method, the systemLayoutFittingSizeDidChange(forChildContentContainer:) method is sent to the parent view controller.
