Can you tell about difficult situations you faced during a project? Why was it interesting and how did you solve it?

During the development of an iOS project, one of the challenging situations was the need to integrate with an outdated API that did not support modern authentication methods. This required implementing workarounds and additional logic for secure storage and updating of tokens.

Another example is optimizing performance when working with a large number of images in a table. Caching and asynchronous loading had to be implemented to avoid interface freezes.

I also faced memory management issues when using complex animations and multithreading, which required careful analysis and profiling of the application.
