ReactiveSwift v6.7.0-rc1 Release Notes

  • 🚦 1. New operator SignalProducer.Type.interval(_:interval:on:) for emitting elements from a given sequence regularly. (#810, kudos to @mluisbrown)

    🚦 1. Signal offers two special variants for advanced users: unserialized and reentrant-unserialized. (#797)

    The input observer of these variants assume that mutual exclusion has been enforced by its callers.

    You can create these variants through four Signal static methods: unserialized(_:), unserializedPipe(_:), reentrantUnserialized(_:) and reentrantUnserializedPipe(_:). These would be adopted by ReactiveCocoa UIKit bindings to improve interoperability with Loop, to tackle some legitimate recursive delivery scenarios (e.g. around first responder management), and also to reduce fine-grained locking in ReactiveCocoa.

    Note that the default behavior of Signal has not been changed — event serialization remains the default behavior.

    🚦 1. SignalProducer offers an unserialized variant via SignalProducer.unserialized(_:). (#797)

    ⏱ 1. TestScheduler can now advanced its clock by TimeInterval. (#828, kudos to @carsten-wenderdel)

    🐎 1. Signal and Properties now use fewer locks, which should translate into minor performance improvements. (#797)

    📚 1. Fixed spelling error in Lifetime.Token class documentation. (#835, kudos to @ansonj)

    🔨 1. As a continued refactoring effort since ReactiveSwift 6.6.0, all unary Signal and SignalProducer operators have been migrated to a new internal representation.

    When debugging your application, the call stacks involving ReactiveSwift may now look cleaner, without the clutter of compiler-generated reabstraction thunks. See #799 for an example.

    🚦 1. New operator SignalProducer.take(until:) that forwards any values until shouldContinue returns false. Equivalent to take(while:), except it also forwards the last value that failed the check. (#839, kudos to @nachosoto)
