What visual behavior will occur when this code executes?
UIView.animate(withDuration: 1.0, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0, options: [], animations: { view.center.x += 150 }, completion: nil)
AThe view will move left with a slight bounce.
BThe view will move right smoothly without any bounce.
CThe view will move right with a pronounced bounce before settling.
DThe view will fade out while moving right.
Step-by-Step Solution
Solution:
  1. Step 1: Understand the damping ratio effect

    A damping ratio of 0.3 is low, causing the animation to overshoot and bounce noticeably.
  2. Step 2: Analyze the animation block

    The view's center.x increases by 150, moving it right.
  3. Final Answer:

    The view moves right with a pronounced bounce. -> Option C
  4. Quick Check:

    Low damping ratio causes bounce [OK]
Quick Trick: Low damping ratio means more bounce [OK]
Common Mistakes:
  • Confusing direction of movement
  • Assuming no bounce with low damping
  • Ignoring the effect of initialSpringVelocity
