on GitHub

This release is meant for use with Xcode 7.2.x and Swift 2.1.x

With this release candidate, RAC 4.0 is API stable. Please report any bugs you may find!

See the CHANGELOG to learn more about the major changes between ReactiveCocoa versions 3 and 4.

This is likely to be the last Release Candidate. If no major issues are found within a week, this will become RAC 4.0 final version! 🎉

New Features

• Added modify, swap, and withValue to MutableProperty (#2617, thanks @andersio and @ikesyo and @NachoSoto for the review!).
• Added signal to PropertyType (#2543, #2622, thanks @andersio and @NachoSoto for the review!).
• Added Signal.empty, equivalent to SignalProducer.empty (#2622, thanks @andersio and @NachoSoto for the review!).
• Added a new operator: SignalProducer.replayLazily, for multicasting (#2639, thanks @NachoSoto and @JaviSoto, @aschuch, @jspahrsummers, @andymatuschak, @kastiglione, @mdiep, @liscio, and others for reviewing!).

Improvements

• The Disposable protocol now requires types to be a class (#2641, thanks to @Adlai-Holler and @NachoSoto for the review!).
• Breaking change: removed default capacity from SignalProducer.buffer() and SignalProducer.replayLazily(). Users are now forced to explicitly decide what the capacity should be in each case (#2672, thanks @mdiep and @neilpa for the review!).

* Added missing UIKit extensions to tvOS target (#2651, thanks @NachoSoto and @neilpa for the review!).. The headers were missing (#2673), so this will be in the next release.
