Apple Developer

I have already make the video tutorial for understanding the basics of the UITableView Controller. Here is the video link! First watch the entire video and get the useful code below of this video.

Great now Please get the important code from this video.

//MARK - UITableViewController REST API CALL
    private func fetchData(){
        guard let url = URL(string: "https://myexample.com/api/which_return_json_data") else {
            return
        }
        let params = "page=1&type=Car"
        var request = URLRequest(url: url)
        request.httpMethod = "POST"
        request.httpBody = params.data(using: .utf8)
        
        let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
            if error != nil {
                print(error.debugDescription)
                return
            }else if data != nil {
                DispatchQueue.main.async {
                    do {
                        let myData = try JSONDecoder().decode(APIResponse<[Cars]>.self, from: data!)
                        if myData.status == 1 {
                            self.cars = myData.data!
                            self.tableView.reloadData()
                        }
                    }catch let error {
                        print(error.localizedDescription)
                    }
                }
            }
        }
        task.resume()
    }

After that please find all the required functions of UITableView Delegate and UITableView DataSource. 

    // MARK: - Table view data source
    
    override func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }
    
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return cars.count
    }
    
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        cell.textLabel?.text = "Car Name : \(cars[indexPath.row].name!)"
        return cell
    }
    
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
       // self.performSegue(withIdentifier: "details", sender: self.cars[indexPath.row])
        
        let story = UIStoryboard(name: "Main", bundle: nil)
        let controller = story.instantiateViewController(identifier: "DetailsController") as! DetailsController
        controller.car = self.cars[indexPath.row]
        self.present(controller, animated: true, completion: nil)
    }
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "details" {
            let controller = segue.destination as! DetailsController
            controller.car = sender as? Cars
        }
    }
