How do I handle errors in Swift's async/await?

In Swift, you can handle errors in async/await using do-catch blocks. You wrap your async call in a do block and catch any errors that might occur.

Can you show me a code example?

Sure! Here's a simple example:

func fetchData() async throws -> Data {
    // Simulate a network call
    throw NSError(domain: "NetworkError", code: 1, userInfo: nil)
}

func loadData() async {
    do {
        let data = try await fetchData()
        print(data)
    } catch {
        print("Error fetching data: \(error)")
    }
}

What if I want to handle multiple errors?

You can catch specific errors by using multiple catch clauses. For example:

do {
    let data = try await fetchData()
} catch let error as NetworkError {
    print("Network error: \(error)")
} catch {
    print("An unexpected error occurred: \(error)")
}
