RxTodo is an iOS application developed using The Reactive Architecture. This project is for whom having trouble with learning how to build a RxSwift application due to lack of references. (as I did 😛)

• The Reactive Architecture
• Using RxDataSources
• Observing model create/update/delete across the view controllers
• Navigating between view controllers
• Immutable models
• Testing with RxExpect

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

  Bad

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

  Good

  viewReactor.titleLabelText
    .bindTo(self.titleLabel.rx.text)

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

  Bad

  viewReactor.login() // Bad: View should not know what ViewReactor does (login)

  Good

  self.loginButton.rx.tap
    .bindTo(viewReactor.loginButtonDidTap) // "Hey I clicked the login button"
  
  self.usernameInput.rx.controlEvent(.editingDidEndOnExit)
    .bindTo(viewReactor.usernameInputDidReturn) // "Hey I tapped the return on username input"

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

  Bad

  struct ProductViewReactor {
    let product: Driver<Product> // Bad: ViewReactor should hide Model
  }

  Good

  struct ProductViewReactor {
    let productName: Driver<String>
    let formattedPrice: Driver<String>
    let formattedOriginalPrice: Driver<String>
    let isOriginalPriceHidden: Driver<Bool>
  }

• iOS 8+
• Swift 3
• CocoaPods
