How can I handle asynchronous code in SwiftUI?

In SwiftUI, you can handle asynchronous code using the async and await keywords. This allows you to write cleaner and more readable asynchronous code.

Can you give me an example of using async/await in a SwiftUI view?

Sure! Here's a simple example:

struct ContentView: View {
    @State private var data: String = ""

    var body: some View {
        VStack {
            Text(data)
            Button("Fetch Data") {
                Task {
                    data = await fetchData()
                }
            }
        }
    }

    func fetchData() async -> String {
        // Simulate a network call
        try? await Task.sleep(nanoseconds: 1_000_000_000)
        return "Data fetched!"
    }
}

What if I need to update the UI after fetching data?

You can update the UI directly in the Task closure after fetching the data, as shown in the example. SwiftUI will automatically refresh the view when the state changes.
