swift – no products or categories on the ViewController in TableView in iOS app with api woocommerce

I begin to create online shop iOS app with connection to site on Woocommerce. I want to insert in TableView products from Woocommerce via API.

Now then I Build the app, simulator launch only white empty screen. In the final result I want to launch iOS app with connection to site on Woocommerce, but I create it step by step, and first step, now, I want to make screen with product or categories from this shop. Why does my iOS app show a blank screen when I try to display WooCommerce products in a TableView via the API?

Product.swift

struct Product: Codable {
    let id: Int
    let name: String
    let price: String
    let regular_price: String?
    let sale_price: String?
    let description: String?
    let short_description: String?
    let images: [ProductImage]?
}

struct ProductImage: Codable {
    let src: String
}

ViewController.swift

ViewController.swift

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var tableView: UITableView!
    private let api = WooCommerceAPI()
    private var products: [Product] = []
    
    override func viewDidLoad() {
        super.viewDidLoad()
        fetchProducts()
    }
    
    func fetchProducts() {
        let urlString = "
        guard let url = URL(string: urlString) else { return }
        
        URLSession.shared.dataTask(with: url) { data, response, error in
            // 1. Проверка ошибок
            if let error = error {
                print("Ошибка сети: \(error)")
                return
            }
            
            // 2. Обработка данных
            guard let data = data else { return }
            do {
                // Здесь декодируйте JSON (например, в массив продуктов)
                print("Данные получены: \(data)")
            } catch {
                print("Ошибка декодирования: \(error)")
            }
        }.resume()
    }
}

WoocommerceAPI.swift

import Foundation


class WooCommerceAPI {
    private let baseURL = "
    private let consumerKey = "ck_1255d3fa39b33e661fc91e9fe17dd16fb4367e5"
    private let consumerSecret = "cs_707ff6ee2e25206a2858c5f288f57dd18acf8358"
    
    func fetchProducts(completion: @escaping ([Product]?) -> Void) {
        let endpoint = "\(baseURL)/products"
        let urlString = "\(endpoint)?consumer_key=\(consumerKey)&consumer_secret=\(consumerSecret)"
        
        guard let url = URL(string: urlString) else {
            completion(nil)
            return
        }
        
        URLSession.shared.dataTask(with: url) { data, response, error in
            if let error = error {
                print("Ошибка: \(error.localizedDescription)")
                completion(nil)
                return
            }
            
            guard let data = data else {
                completion(nil)
                return
            }
            
            do {
                let products = try JSONDecoder().decode([Product].self, from: data)
                completion(products)
            } catch {
                print("Ошибка декодирования: \(error.localizedDescription)")
                completion(nil)
            }
        }.resume()
    }
