What are the SwiftUI apis for making network calls?

SwiftUI itself does not provide specific APIs for making network calls. Instead, SwiftUI is designed to work seamlessly with other frameworks and technologies that handle networking. For making network calls in a SwiftUI app, you would typically use Swift's URLSession or other networking libraries like Alamofire. These can be integrated into your SwiftUI app to fetch data from the network and then update your SwiftUI views accordingly.

For example, you can use URLSession to perform network requests and then use the data to update your SwiftUI views. Here's a simple example of how you might fetch data using URLSession:

import SwiftUI

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

    var body: some View {
        Text(data)
            .onAppear {
                fetchData()
            }
    }

    func fetchData() {
        guard let url = URL(string: "https://api.example.com/data") else { return }

        URLSession.shared.dataTask(with: url) { data, response, error in
            if let data = data, let string = String(data: data, encoding: .utf8) {
                DispatchQueue.main.async {
                    self.data = string
                }
            }
        }.resume()
    }
}

This example demonstrates how to perform a network request and update a SwiftUI view with the fetched data. SwiftUI's declarative nature allows you to easily update the UI in response to changes in your data model.
