How to use multi labels in UITableView? - swift

Question

I get data from JSON (First name, last name and email) but I'm only able to show first name in UITableView. I tried my best but I couldn't make it work. Following is my code.
import UIKit
struct User: Codable {
let firstName: String
let lastName: String
let email: String
enum CodingKeys: String, CodingKey {
case firstName = "first_name"
case lastName = "last_name"
case email = "email"
}
}
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var tableview: UITableView!
private var dataSource = [User]() {
didSet {
self.tableview.reloadData()
}
}
override func viewDidLoad() {
super.viewDidLoad()
self.tableview.register(UITableViewCell.self, forCellReuseIdentifier: "groupCell")
self.tableview.dataSource = self
self.tableview.delegate = self
let url = URL(string: "https://x.com/x.php")
URLSession.shared.dataTask(with: url!, completionHandler: { [weak self] (data, response, error) in
guard let data = data, error == nil else {
print(error?.localizedDescription ?? "An error occurred")
return
}
DispatchQueue.main.async {
self?.dataSource = try! JSONDecoder().decode([User].self, from: data)
}
}).resume()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
tableview.reloadData()
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return dataSource.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "groupCell", for: indexPath)
let user = self.dataSource[indexPath.row]
cell.textLabel?.text = user.firstName
// cell.textLabel?.text = user.lastName If I write this line then it only shows last name
return cell
}
}

You can use UITableViewCell.CellStyle.subtitle, like so:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell: UITableViewCell! = tableView.dequeueReusableCell(withIdentifier: "groupCell")
if cell == nil {
cell = UITableViewCell(style: .subtitle, reuseIdentifier: "groupCell")
}
let user = self.dataSource[indexPath.row]
cell.textLabel?.text = user.firstName + " " + user.lastName
cell.detailTextLabel?.text = user.email
return cell
}
You do not need to register cell, so DELETE following line:
tableview.register(UITableViewCell.self, forCellReuseIdentifier: "groupCell")
