Alt

Another Flux implementation for Swift. It provides concept of “one-way data flow” with type-safe modules by Swift language.

Usage

Step 1: Define Action

Create struct that implements protocol Action.

struct TodoActions {
    struct Create : Action {
        let title : String
    }
}

Step 2: Define Store and register action

Create a Store class, which implement Store protocol with a typealiase State
Use Alt.getStore(YourStore.self) to get a singleton instance of the store
Bind Actions to handers, where the store update it states.
Invoke self.emitChange() to notify listeners about change of states in Store

class TodoStore : Store {
    // define a typealias for the state of the model
    typealias State = [Todo]

    // and add a property of the State
    var state : State!

    // Set the initial state of the Store
    static func getInitialState() -> State {
        return []
    }

    required init() {
        self.bindAction(TodoActions.Create.self, handler: self.onCreate)

        // alternatively, bind action with a block
        self.bindAction(TodoActions.Create.self) { [weak self] (action) -> () in
            self?.state.append(Todo(title: action.title))
        }
    }

    private func onCreate(action: TodoActions.Create) {
        self.state.append(Todo(title: action.title))
        self.emitChange()
    }
}

Step 3: Listen store’s event at View

self.todoStore.listen { (state) -> (Void) in
    self.tableView.reloadData()
}

Step 4: Create and dispatch an Action

TodoActions.Create(title: "New ToDo").dispatch()
