Lightweight observations and bindings in Swift

hanson's Issues

Controller cannot release after observing a notification.

Hello, I got an issue that the view controller cannot release when observing a notification like this.

let observable = NotificationCenter.default.observable(for: Notification.Name.UIApplicationDidEnterBackground)
observe(observable) { notification in
    print("Application did enter background")
}

How to fix it ? Thanks.

Observing Array

How would you go about observing an array using Hanson?

observe one property of complex object?

I am not quite sure how to approach this and think my understanding of Hanson is not yet up-to-speed. I have a complex object from another repo. It is very deep and async-oriented. I want to track at least one property from it, and prefer not to tap into their repo to make changes. Without those changes, is something like this possible?

I want to track the duration property of the youtube API return values from player within youtubeKit, if that helps. And i understand if this is too complex to ask! thx...

How to listen to changing the text of UITextFiled in a xib?

Hello, Thank you very much for your library !! I have a problem: when I input text to a UITextFiled (from xib), how do I listen for changes in text ?

Bind error

Hi. Thank you for your work. I've been looking for a library just like yours. It's great for implementing MVVM without having to add RxSwift and so.

I'm getting an error when I try to use the bind function. For instance, if I write:

bind(wsSuccess, to: model.wsFBSuccess) //both properties are Observable(false)

I get a Xcode error saying "Missing argument for parameter #3 in call". I don't know if you have changed the function signature from the one appearing in the readme but autocomplete is only offering me: bind(Int32, UnsafePointer!, socklen_t) which seems unrelated to your library.

What am I doing wrong?

Please update the version available via Cocoapods

The current one still doesn't support observing NotificationCenter notifications.

Use of unresolved identifier 'observe' for non-ui class

import UIKit
import Hanson

final class RootCoordinator {
    static func presentTodoLists(list:[TodoModel]) -> UINavigationController {
        // Adding observer listening to model change
        observe(todosObservable) { event in

        }
    }
}

Hello @utemissov ,
Is there anyway that I can observe a value inside a kind of non-ui class ?

Is there a way to initialize observable properties to nil?

Let's say I'd like to observe a property of type UIImage. Is there a way of make it nil by default?

Something like:

let observableImage : UIImage? = Observable(nil)

Will you consider integrating reactive property?

For example:

observe(observable) { (e) in
    cb();
}

cb();

But with reactive property I can code like this:

observable.subscribe { (e) in
    cb();
}
