A code for demonstrating how to use URLSession to send network request from iOS app

NetworkService.swift

struct Name: Decodable {
    let firstName: String
    let lastName: String
}

final class NetworkService {
  func loadSampleData(completion: @escaping (Result<Name, Error>) -> Void) {

        let url = URL(string: "www.google.com")!

        let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
            
            let decoder = JSONDecoder()
            let responsePayload = try! decoder.decode(Name.self, from: data!)
            completion(.success(responsePayload))

        }
        task.resume()
    }
}

//How to use API

NetworkService().loadSampleData { result in

}
