Core

NSObject+rx

No need to declare a DisposeBagin every class.

class MyViewController: UIViewController {
-	let disposeBag = DisposeBag()
}

Every class that inherits from NSObject automatically adds a lazy variable disposeBag

Memoization

Wikipedia: In computing, memoization or memoisation is an optimization technique used primarily to speed up computer programs by storing the results of expensive function calls and returning the cached result when the same inputs occur again.

See source for more information

Observable.pairwise()

Triggers on the second and subsequent triggerings of the input observable.
The Nth triggering of the input observable passes the arguments from the N-1th and Nth triggering as a pair.

See RxMarbles.com#pairwise for more information

User.current.rx.state
    .pairwise()
    .filter { $0.0 == .loggedIn && $0.1 == .loggedOut }
    .subscribe { _ in
        logger.warning("User logged out!")
    }
.addDisposableTo(disposeBag)

Improvement over the Observable.zip(sequence.skip(1), sequence)
