Swift one-way bindings between ReactiveCocoa SignalProducers and views.

A work-in-progress.

Example — Reading values from text fields and combining them:

// Allow logging in when a username and password have been entered and no 
// account is currently logged in.
let canLogIn = combineLatest(
        usernameTextField.textProducer,
        passwordTextField.textProducer,
        LoginManager.loggedIn.producer
    )
    .map { username, password, loggedIn in
        return username.characters.count > 0 && password.characters.count > 0 && !loggedIn
    }

Example — Binding a signal producer to an activity indicator:

// Animate the Loading indicator while logging in OR logging out.
let isLoading = combineLatest(
        logInAction.executing.producer,
        logOutAction.executing.producer
    )
    .map { loggingIn, loggingOut in 
        return loggingIn || loggingOut
    }
activityIndicator.animatingEndpoint.bind(isLoading)

Example — Binding an action to a button:

// Executes `logOutAction` when tapped, ignoring the 'sender' by sending `()` 
// as the Action's input.
logOutButton.executor
    .ignorePayloads()
    .bind(logOutAction)
