Can you explain how AutoLayout system works in interface components?

AutoLayout is a system for automatically arranging interface elements in iOS, which allows describing positioning and sizing rules using constraints.

Internally, AutoLayout works as follows:

1. Each element has a set of constraints that describe its position and size relative to other elements or the superview.
2. The system gathers all constraints into a single system of equations.
3. A solver computes the frame values of elements that satisfy all constraints.
4. If constraints are insufficient or conflict, the system tries to find a compromise or issues warnings.

This allows creating adaptive interfaces that display correctly on different devices and orientations without manual coordinate calculations.
