DetailsViewController

We will use DetailsViewController to present the details of a Todo item and modify it. We will have three textField and a switch. We will observe the changes in the UI and modify the State and backend. The code is as follows:

import UIKit import ReactiveCocoa import ReactiveSwift class DetailsViewController: UIViewController {     @IBOutlet weak var txtFieldName: UITextField!     @IBOutlet weak var txtFieldDescription: UITextField!     @IBOutlet weak var txtFieldNotes: UITextField!     @IBOutlet weak var switchCompleted: UISwitch!     var viewModel = TodoViewModel(todo: nil)     override func viewDidLoad() {         super.viewDidLoad()         store.selectedTodo.startWithValues {             todos in             let model = todos.first!  self.txtFieldName.text = model.name ...
