## What is NxEnabled?

It's a fairly common case, when the `enabled` state of button depends on some textable elements such as TextView, TextField. So this library allows the simplest way to achive this purpose with only few lines of code.

## Getting started :rocket:

Typical login screen with short, beautiful validation code:

```swift

loginButton.isEnabled(by: usernameTextField, passwordTextField) { username, password in

    username.characters.count > 5 && password.characters.count > 5

}

```

you can also combine together `UITextView` with `UITextField`'s:

```swift

signUpButton.isEnabled(by: firstnameTextField, lastnameTextField, bioTextView) { firstname, lastname, bio in

    return /* validation value */

}

```

*So there is also oportunity to add not UI element:*

* Implement `Textable` protocol

  

* Be a successor from `NSObject`

  

* Not forget about `dynamic` label for property

  

* Done.

  

```swift

class Object: NSObject, Textable {

    dynamic var value: String?

    var textKey: String {

        return "value"

    }

}

```

### NOTE:

**One important case is that you should clear button's bag. It removes all observers from textable elements. Usually it needs to do in `deinit` method.**

```swift

deinit {

    signUpButton.clearBag()

}

```

### **Now library allows to add textable elements up to six. :clap:**
