iOS Swift - Animations

You want to animate a card flipping effect between a front and back view using matchedGeometryEffect. Which approach correctly achieves this?

AUse the same <code>id</code> and <code>namespace</code> on front and back views, toggle visibility, and animate rotation

BUse different <code>id</code> values for front and back views with the same namespace

CApply matchedGeometryEffect only to the front view and toggle the back view without it

DUse matchedGeometryEffect with no namespace to link the views

Step-by-Step Solution

Solution:

Step 1: Understand matchedGeometryEffect for flipping
To animate a flip, both front and back views must share the same id and namespace to link their geometry.
Step 2: Combine with rotation animation
Toggling visibility and animating rotation creates the flip effect smoothly.
Final Answer:
Use the same id and namespace on front and back views, toggle visibility, and animate rotation -> Option A
Quick Check:
Same id + namespace + rotation = flip animation [OK]

Quick Trick: Flip needs same id, namespace, and rotation animation [OK]
