Can you explain what is meant by the term hugging priority and how it is used in context

In iOS, the term hugging priority (content hugging priority) refers to the priority with which a UIView tries to maintain its minimal possible size without stretching more than necessary. It is part of the auto layout system that helps determine how a view will resize when there is a shortage or excess of space.

The higher the hugging priority value, the more the view "resists" increasing its size. For example, if two views conflict in width, the view with the lower hugging priority will stretch, while the one with the higher priority will stay closer to its intrinsicContentSize.

Example usage:

let label = UILabel()
label.setContentHuggingPriority(.defaultHigh, for: .horizontal)

Here, we are indicating that the label should try not to stretch horizontally, occupying exactly the space needed to display the text.
