RxTodo is an iOS application developed using RxSwift and MVVM design pattern. This project is for whom having trouble with learning RxSwift and MVVM due to lack of references. (as I did 😁)

• MVVM design pattern
• Using RxDataSources
• Observing model create/update/delete across the view controllers
• Navigating between view controllers
• Immutable models and view models

• View doesn't have control flow. View cannot modify the data. View only knows how to map the data.

  Bad

  viewModel.title
      .map { $0 + "!" } // Bad: View should not modify the data
      .bindTo(self.titleLabel)

  Good

  viewModel.title
      .bindTo(self.titleLabel)

• View doesn't know what ViewModel does. View can only communicate to ViewModel about what View did.

  Bad

  viewModel.login() // Bad: View should not know what ViewModel does (login)

  Good

  self.loginButton.rx_tap
      .bindTo(viewModel.loginButton)
      // "Hey I clicked the login button"
  
  self.usernameInput.rx_controlEvent(.EditingDidEndOnExit)
      .bindTo(viewModel.usernameInputDidReturn)
      // "Hey I tapped the return on username input"

• Model is hidden by ViewModel. ViewModel only exposes the minimum data so that View can render.

  Bad

  class ProductViewModel {
      let product: Driver<Product> // Bad: ViewModel should hide Model
  }

  Good

  class ProductViewModel {
      let productName: Driver<String>
      let formattedPrice: Driver<String>
      let formattedOriginalPrice: Driver<String>
      let originalPriceHidden: Driver<Bool>
  }

• iOS 8+
• Swift 2.2
• CocoaPods (I used 1.0.0)
