What's new in ReactiveCocoa 5.0.3

Apr 8, 2017
  • Addition:
  • New KVO API: NSObject.reactive(self:).signal(forKeyPath:). (#3413, kudos to @Burgestrand)
  • New binding targets for UINavigationItem and UITabBarItem. (#3444, kudos to @Marcocanc)
  • New binding targets for UIFeedbackGenerator and its subclasses. (#3447, kudos to @Marcocanc)
  • Changes:
  • NSObject.reactive(self:).values(forKeyPath:) is deprecated and replaced by NSObject.reactive(self:).producer(forKeyPath:). (#3413)
  • The KVO API now supports object values that are of native Swift classes properly. (#3439, kudos to @andersio)
  • A bug that could lead to deadlocks and unexpected nil in the KVO API on any arbitrary key path was fixed. (#3439)
  • Continuous text signals of UITextField now emits the latest value for all editing events emitted. In other words, replacements due to autocompletions are now covered by the signals. (#3442 , kudos to @andersio)
  • Fixed a ObjC swizzling bug that caused ActionProxy not working well with KVO and RAC method interception. (#3435, kudos to @andersio)

New in ReactiveCocoa 5.0.2 (Mar 31, 2017)

  • Addition:
  • New binding target for UITextField: textColor. (#3410)
  • Changes:
  • Fixed a bug causing KVO deallocation exception when using values(forKeyPath:) with a nested key path. (#3418)
  • Fixed a bug causing types with DelegateProxy backed extensions crashed upon deallocation in a specific circumstance. (#3425)
  • Setting target and action of NSControls no longer disrupts the functionality of its RAC extensions. (#3394)

New in ReactiveCocoa 5.0.1 (Mar 11, 2017)

New in ReactiveCocoa 5.0.0 (Jan 20, 2017)

  • This release refocuses ReactiveCocoa on reactive bindings for Apple’s Cocoa and Cocoa Touch frameworks.

  • The new reactive bindings build on the excellent work done by @neilpa on Rex. AppKit and UIKit objects are extended via a reactive property that houses Signals and BindingTargets to be used with ReactiveSwift’s

New in ReactiveCocoa 4.0 Alpha 1 (Oct 12, 2015)

  • Signal operators are protocol extensions:
  • The biggest change from RAC 3 to RAC 4 is that signal and producer operators are implemented as protocol extensions instead of global functions. This is similar to many of the collection protocol changes in the Swift 2 standard library.
  • This enables chaining signal operators with normal dot-method calling syntax. Previously the custom |> was required to enable chaining global functions without a mess of nested calls and parenthesis.
  • Additionally, this means that SignalProducer operators are less "magic". In RAC 3 the Signal operators were implicitly lifted to work on SignalProducer via |>. This was a point of confusion for some, especially when browsing the source looking for these operators. Now as protocol extensions, the SignalProducer operators are explicitly implementated in terms of their Signal counterpart when available.
  • Removal of |> custom operator:
  • As already alluded to above, the custom |> operator for chaining signals has been removed. Instead standard method calling syntax is used for chaining operators.
  • Event.Sink is now a function:
  • With the removal of SinkType in Swift 2, the Event.Sink type is now just a function Event -> ().
  • Event cases are no longer boxed:
  • The improvements to associated enum values in Swift 2 mean that Event cases no longer need to be Boxed. In fact, the Box dependency has been removed completely from RAC 4.
  • Replacements for the start and observer overloads:
  • The observe and start overloads taking next, error, etc. optional function parameters have been removed. This was necessitated by the change to Event.Sink becoming a function type which introduced an unresolvable ambiguity. They've been replaced with methods taking a single function with the target Event case -- observeNext, startWithNext, and the same for error and completed. See #2311 and #2318 for more details.
  • Renamed try and catch operators:
  • The try and catch operators were renamed because of the addition of the error handling keywords with the same name. They are now attempt and flatMapError respectively. Also, tryMap was renamed to attemptMap for consistency.
  • Added flatten and flatMap for signal-of-producers:
  • This fills a gap that was missing in RAC 3. It's a common pattern to have a hot Signal of values that need to be mapped to "work" -- SignalProducer. The addition of flatten and flatMap over signals-of-producers makes it easy to serialize (Concat) or parallelize (Merge) the work, or only run the most recent (Latest).
  • Renaming T and E generic parameters:
  • Probably coming to later alpha. See #2212 and #2349.
  • Renaming Event.Error to Event.Failed:
  • Maybe coming to a later alpha. See #2360.
