How to implement animation of changing constraints parameters in UI?

In iOS, to animate changes to constraints, the layoutIfNeeded() method is usually used inside a UIView animation block. First, the constraint values are changed, then an animation is called in which layoutIfNeeded() is invoked to update the layout of the elements with animation.

Example:

// Change the constraint
self.myConstraint.constant = 50

UIView.animate(withDuration: 0.3) {
    self.view.layoutIfNeeded()  // animate the changes
}

Thus, constraint changes are smoothly animated, and the UI updates without abrupt jumps.
