UIKit - SwiftUI Comparison

ContentView.swift

import SwiftUI

struct ContentView: View {
    @ObservedObject var viewModel: ContentVM

    var body: some View {
        NavigationView {
            List(viewModel.values, id: \.self) { value in
                Text(value)
            }.navigationBarTitle("Our Cells")
        }
    }
}

UContentVC.swift

import UIKit
import Combine

class UNavContentVC: UINavigationController {
    init(viewModel: ContentVM) {
        super.init(rootViewController: UContentVC(viewModel: viewModel))
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

class UContentVC: UIViewController, UITableViewDataSource {
    private var cancelables = [AnyCancellable]()
    let tableView = UITableView()
    let viewModel: ContentVM

    init(viewModel: ContentVM) {
        self.viewModel = viewModel
        super.init(nibName: nil, bundle: nil)
    }

    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        self.title = "Our Cells"
        self.navigationController?.navigationBar.prefersLargeTitles = true
        self.tableView.frame = self.view.bounds
        self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "someCell")
        self.tableView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        self.view.addSubview(self.tableView)
        self.tableView.dataSource = self

        viewModel.$values.sink { [weak self] _ in
            self?.tableView.reloadData()
        }.store(in: &cancelables)
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        viewModel.values.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "someCell", for: indexPath)
        cell.textLabel?.text = viewModel.values[indexPath.row]
