Explain the concept of compression resistance and its significance.

Compression Resistance is a property of iOS interface elements that determines how much an element tries to maintain its minimum size when space is compressed.

For example, if you have a UILabel with long text and limited space, the compression resistance indicates whether this label will compress (truncate or wrap) or maintain its minimum size.

The compression resistance value is set using priorities (UILayoutPriority) for horizontal and vertical directions. The higher the priority, the more the element resists shrinking.

This is important when working with Auto Layout to properly manage element behavior when the screen or container size changes, avoiding unwanted truncation or overlapping of elements.
