How to fill out error handling in swift

1. To fill out error handling in Swift, follow these steps:
2. Identify the section of code where you want to handle errors.
3. Use the 'do' keyword to start a new error-handling section.
4. Write the code that may potentially throw an error inside the 'do' block.
5. Use the 'try' keyword before any statement that can potentially throw an error.
6. Use the 'catch' block to handle specific errors. You can have multiple 'catch' blocks for different types of errors.
7. Inside the 'catch' blocks, write the code to handle the specific error. This could involve displaying an error message or taking alternative actions.
8. Optionally, you can use the 'finally' block to execute code that should be run regardless of whether an error occurred or not.
9. If you don't want to handle the error locally, you can propagate it using the 'throw' keyword.
10. Make sure to handle all potential errors to prevent crashes in your code.
11. Test the error handling code thoroughly to ensure it works as expected.
