If you're using RxSwift, you've probably encountered the following code more than a few times.

class MyObject: Whatever {
	let disposeBag = DisposeBag()
	...
}

You're actually not the only one; it has been typed many, many times.

Instead of adding a new property to every object, use this library to add it for you, to any subclass of NSObject.

thing
  .bind(to: otherThing)
  .disposed(by: rx.disposeBag)

Sweet.

It'll work just like a property: when the instance is deinit'd, the DisposeBag gets disposed. It's also a read/write property, so you can use your own, too.

If you want to add a DisposeBag to an Object that does not inherit from NSObject, you can also implement the protocol HasDisposeBag, and you're good to go. This protocol provides a default DisposeBag called disposeBag.

Add to your Podfile:

pod 'NSObject+Rx'

And that'll be 👌

Add to Cartfile:

github "RxSwiftCommunity/NSObject-Rx"

Add frameworks to your project (no need to "copy items if needed")

Run carthage update or carthage update --platform ios if you target iOS only

Add run script build phase /usr/local/bin/carthage copy-frameworks with input files being:

$(SRCROOT)/Carthage/Build/iOS/RxSwift.framework
$(SRCROOT)/Carthage/Build/iOS/NSObject_Rx.framework

And rule ✌️

Source files are in the root directory. We use CocoaPods to develop, check out the unit tests in the Demo project.
