Call API when app is in background

I use SwiftUi I want to call API when app is in background and send notifications to users

This is my code to call API. I found this way from Apple Dec for Background fetch But this for UIkit

Code Block }        .onAppear(perform: loadData)
    }
    func loadData() {
        guard let url = URL(string: "My API") else {
            print("Invalid URL")
            return
        }
        let request = URLRequest(url: url)
        URLSession.shared.dataTask(with: request) { data, response, error in
            if let data = data {
                if let decodedResponse = try? JSONDecoder().decode([Result].self, from: data) {
                    DispatchQueue.main.async {
                        self.results = decodedResponse
                    }
                    return
                }
            }
            print("Fetch failed: \(error?.localizedDescription ?? "Unknown error")")
        }.resume()
    }
}
