# Cancellor

Bind multiple cancellables to the lifetime of another object like your view controller.

## Usage

Import **Cancellor** and subscribe your publishers inside an `ownedCancellables` block. When your view controller is dismissed any active subscriptions will get cancelled automatically. 

```swift

import Cancellor

class MyViewController: UIViewController {

  override func viewDidLoad() {

    ownedCancellables {

      myPublisher1.sink(...)

      myPublisher2.sink(...)

      myPublisher3.assign(to: ..., on: ...)

    }

  }

}

```

To tie a single subscription to the lifetime of another object use:

```swift

class ViewModel: NSObject { ... }

let vm = ViewModel(...)

...

myPublisher

  .sink(...)

  .owned(by: vm)

```

## Import

Add the following dependency to your **Package.swift** file:

```swift

.package(url: "https://github.com/icanzilb/Cancellor", from: "0.2.0")

```
