Share a case where you failed to achieve the expected result and how you handled the situation.

In one of my iOS projects, I tried to implement a complex animation using Core Animation, but I faced a problem: the animation did not work correctly on some devices, especially under low performance conditions. Initially, I tried to optimize the animation code, but it did not yield the desired results.

To handle the situation, I:

• Conducted profiling with Instruments to identify bottlenecks.
• Simplified the animation by reducing the number of layers and effects.
• Used lighter animation methods, such as UIViewPropertyAnimator instead of CAAnimation.

As a result, the animation started working smoothly on all target devices, and I realized the importance of testing on real devices and profiling performance.
