How can I handle errors in SwiftUI?

In SwiftUI, you can handle errors using the do-catch statement. You can also use Result types for better error management.

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

Sure! Here's a simple example:

do {
    let data = try fetchData()
    // Use the data
} catch {
    print("Error fetching data: \(error)")
}

What about using Combine for error handling?

With Combine, you can use the catch operator to handle errors in your publishers. For example:

fetchDataPublisher()
    .catch { error in
        Just([]) // Return an empty array on error
    }
    .sink(receiveCompletion: { completion in
        // Handle completion
    }, receiveValue: { data in
        // Use the data
    })
