What are some effective error handling techniques in Swift?

In Swift, you can use several techniques for error handling, such as using do-catch blocks, throwing functions, and optional try.

Can you explain how do-catch blocks work?

Sure! A do-catch block allows you to handle errors by trying a piece of code in the 'do' section and catching errors in the 'catch' section.

What is the difference between throwing functions and optional try?

Throwing functions can propagate errors, while optional try returns nil if an error occurs, allowing for safer error handling.

Are there best practices for error handling in Swift?

Yes, some best practices include using specific error types, providing meaningful error messages, and avoiding excessive use of force unwrapping.
