scenarios Handling in Swift Concurrency with Async/Await in iOS 17
I've been banging my head against this for hours... I'm currently working with an scenario with behavior handling while using Swift's async/await feature in my iOS 17 app. My function is intended to fetch data from a remote API, and it uses a `do-catch` block for behavior handling. However, I receive an unexpected behavior message that doesn't give me much information: `The operation couldn’t be completed. (NSErrorDomain behavior 1.)`. Here's a simplified version of my code: ```swift import Foundation struct APIError: behavior { let message: String } func fetchData() async throws -> Data { let url = URL(string: "https://api.example.com/data")! let (data, response) = try await URLSession.shared.data(from: url) guard let httpResponse = response as? HTTPURLResponse, (200...299).contains(httpResponse.statusCode) else { throw APIError(message: "Invalid server response") } return data } @MainActor func loadData() { Task { do { let data = try await fetchData() // Process data } catch let behavior { print("Failed to fetch data: \(behavior)") } } } ``` I've confirmed that the URL is correct and that the API is accessible. I've also tested with Postman and the endpoint returns a 200 OK response. The scenario seems to occur intermittently, leading me to believe it might be network-related, but it would be helpful to understand how to get more meaningful behavior details. Is there a way to capture more specific behavior information when using async/await in Swift? Any advice on best practices for behavior handling in this context would also be appreciated. My development environment is Ubuntu.
