What is lazy loading in iOS apps and how does it work?

Lazy loading is a design pattern that delays the initialization of an object until it's needed. In iOS apps, this means loading resources like images or data only when they are about to be displayed, which improves performance and reduces memory usage.

Can you give me an example of how to implement lazy loading in a UITableView?

Sure! You can implement lazy loading in a UITableView by using the cellForRowAt method to load images asynchronously. For instance, you can use a placeholder image while the actual image is being downloaded.

What are the benefits of using lazy loading?

The benefits include faster initial load times, reduced memory consumption, and improved user experience as content loads as needed.

Are there any downsides to lazy loading?
