How can I convert a RACDisposable to a Disposable in ReactiveCocoa 5?

Question

In ReactiveCocoa 5, how can I convert a RACDisposable to a Disposable? If I try to add a RACDisposable to a CompositeDisposable, I get "Binary operator '+=' cannot be applied to operands of type 'CompositeDisposable' and 'RACDisposable'".

Answer 1

Use a closure to wrap the Objective-C things.

let disposable = CompositeDisposable()

let racDisposable = RACDisposable()

disposable += {
    racDisposable.dispose()
}
