When fetching an API in SwiftUI, how can the message "The data could not be read due to incorrect formatting" in the console be obtained?

edit

One way to obtain the "The data could not be read due to incorrect formatting" message in the console is by adding a catch block to handle any errors that may occur while parsing the data. For example:

struct ContentView: View {
    @State var data: [Post] = []

    var body: some View {
        List(data) { post in
            Text(post.title)
        }
        .onAppear() {
            fetchData()
        }
    }

    func fetchData() {
        guard let url = URL(string: "https://jsonplaceholder.typicode.com/posts") else {
            return
        }

        URLSession.shared.dataTask(with: url) { data, response, error in
            if let error = error {
                print(error.localizedDescription)
                return
            }

            if let data = data {
                do {
                    let decodedData = try JSONDecoder().decode([Post].self, from: data)
                    DispatchQueue.main.async {
                        self.data = decodedData
                    }
                } catch {
                    print("The data could not be read due to incorrect formatting")
                }
            }
        }.resume()
    }
}

In this example, if the JSON format is incorrect, the "The data could not be read due to incorrect formatting" message will be printed to the console. If there are any other types of errors, they will be printed to the console as well.
