This is the first release candidate of ReactiveSwift 4.0. It requires Swift 4.1.

Operators

  1. New method collect(every:on:skipEmpty:discardWhenCompleted:) which delivers all values that occurred during a time interval (#619, kudos to @Qata)
  2. debounce now offers an opt-in behaviour to preserve the pending value when the signal or producer completes. You may enable it by specifying discardWhenCompleted as false (#287, kudos to @Qata)
  3. New property operator: filter (#586, kudos to @iv-mexx)
  4. New operator merge(with:) (#600, kudos to @ra1028)
  5. New operator map(value:) (#601, kudos to @ra1028)
  6. SignalProducer.merge(with:), SignalProducer.concat, SignalProducer.prefix, SignalProducer.then, SignalProducer.and, SignalProducer.or, SignalProducer.zip(with:), SignalProducer.sample(with:), SignalProducer.sample(on:), SignalProducer.take(until:), SignalProducer.take(untilReplacement:), SignalProducer.skip(until:), SignalProducer.flatMap, SignalProducer.flatMapError, SignalProducer.combineLatest(with:), Signal.flatMap, Signal.flatMapError, Signal.withLatest(from:) and Property.init(initial:then:) now accept SignalProducerConvertible conforming types (#610, #611, kudos to @1028)

Changes: Conditional Conformance

  1. For Swift 4.1 and above, BindingSource conformances are required to have Error parameterized as exactly NoError. As a result, Signal and SignalProducer are now conditionally BindingSource. (#590, kudos to @NachoSoto and @andersio)
  2. For Swift 4.1 and above, Signal.Event and ActionError are now conditionally Equatable. (#590, kudos to @NachoSoto and @andersio)

Interoperability

  1. Result now interoperates with SignalProducer n-ary operators as a constant producer (#606, kudos to @Qata)

Miscellaneous

  1. Lifetime may now be manually ended using Lifetime.Token.dispose(), in addition to the existing when-token-deinitializes semantic. (#641, kudos to @andersio)
  2. Bag may now be initialised with a sequence of elements. (#609, kudos to @ra1028)
  3. Non-class types may now conform to ReactiveExtensionProvider. (#636, kudos to @ra1028)
