How can I handle errors in my iOS app?

You can handle errors in your iOS app using Swift's error handling model, which includes do-catch blocks.

Can you give me an example of using do-catch?

Sure! Here's a simple example:

func fetchData() throws {
    // code that might throw an error
}

do {
    try fetchData()
} catch {
    print("Error: \(error)")
}

What about handling network errors?

For network errors, you can check the error type in the catch block and handle different cases accordingly.

Is there a way to show user-friendly error messages?

Yes! You can create a function to map error types to user-friendly messages and display them in your UI.
