What is Auto Layout?

A system for creating adaptive user interfaces (UI) that allows defining the position and size of UI elements through a set of constraints or rules. It automatically adjusts the layout when the screen size, device orientation, or text changes.

Key concepts of Auto Layout:

• Layout Anchors: An object-oriented API for creating constraints.
• Layout Guides: Objects representing layout areas such as scroll boundaries or safe areas.
• Intrinsic Content Size: The preferred size of an element based on its content.
• Content Hugging Priority: The priority with which an element resists increasing its size.
• Content Compression Resistance Priority: The priority with which an element resists decreasing its size.
