Which assignments or topics proved to be the most difficult for you, and how did you overcome them?

One of the most challenging topics for me was the basics of working with asynchronous programming and multithreading in iOS, especially understanding GCD (Grand Central Dispatch) and proper thread management for UI updates.

To overcome these difficulties, I:

• Studied official documentation and examples from Apple.
• Practiced writing small projects using DispatchQueue.
• Used debugging and logs to understand the order of code execution.
• Discussed questions with more experienced colleagues and on specialized forums.

This approach helped me better understand how to safely and efficiently perform background tasks and update the interface.
