6.3.0

This is the third minor release of ReactiveSwift 6.

Additions

1. Property and MutableProperty can now be used as property wrapper. Note that they remain a reference type container, so it may not be appropriate to use them in types requiring value semantics. (#781)

   class ViewModel {
     @MutableProperty var count: Int = 0
   
     func subscribe() {
       self.$count.producer.startWithValues {
         print("`count` has changed to \(count)")
       }
     }
   
     func increment() {
       print("count prior to increment: \(count)")
       self.$count.modify { $0 += 1 }
     }
   }

2. When combineLatest or zip over a sequence of SignalProducers or Propertys, you can now specify an optional emptySentinel parameter, which would be used when the sequence is empty.

   This becomes relevant, when the sequence of producers is calculated from some other Signal and the signal resulting from the joined producers is observed. If no value is sent when the sequence is empty, the observer gets terminated silently, and, e.g., the UI would not be updated.

   (#774, kudos to @rocketnik)

Miscellaneous

1. Test dependencies should no longer be built for SwiftPM users, as a result of ReactiveSwift moving to swft-tools-version: 5.2. (#784)

6.2.1

This is a patch release of ReactiveSwift 6.2.

Changes

• Improved performance of aggregating a sequence of Signal and SignalProducer using the static combineLatest and zip operators. (#773, kudos to @rocketnik)

• Fixed the SignalProducer.debounce operator which does not deliver any value if having been started more than once. (#772, kudos to @gpambrozio)

6.2.0

Changes

1. FlattenStrategy.throttle is introduced. (#713, kudos to @inamiy)

   Given a first inner stream, all subsequent inner streams sent by the upstream would be dropped until the first inner stream has completed. The whole process repeats indefinitely until the upstream terminates. The behavior is akin to throttle(_:on:) except for operating in the domain of streams instead of time.

2. The package file of ReactiveSwift now declares supported platforms. (#761, kudos to @ikesyo)

3. Renamed filterMap to compactMap and deprecated filterMap (#746, kudos to @Marcocanc)

6.1.0

1. Support Swift 5.1 and Xcode 11 (#739, thanks @NachoSoto!)

2. Add all and any operators with array of arguments (#735, kudos to @olejnjak)

   let property = Property.any([boolProperty1, boolProperty2, boolProperty3])

3. Fixed Result extensions ambiguity (#733, kudos to @nekrich)

4. Add <~ binding operator to Signal.Observer (#635, kudos to @Marcocanc)

6.0.0

This release drops support for Swift 4.2 (Xcode 10/10.1) and removes the dependency on antitypical/Result. 🎉 (#702, kudos to @NachoSoto and @mdiep)

Upgrade to 6.0.0

• If you have used Result only as dependency of ReactiveSwift, remove all instances of import Result, import enum Result.NoError or import struct Result.AnyError and remove the Result Framework from your project.
• Replace all cases where NoError was used in a Signal or SignalProducer with Never
• Replace all cases where AnyError was used in a Signal or SignalProducer with Swift.Error

5.0.1

This release requires Swift 4.2 or above.

Fix the warnings in Xcode 10.2.

5.0.0

This is the first release of ReactiveSwift 5.0. It requires Swift 4.2 or above.

Xcode 10.2 Support

1. Swift 5.0 and Xcode 10.2 support (#707 and #711, kudos to @ChristopherRogers and @ikesyo)

Operators

1. New operator materializeResults and dematerializeResults (#679, kudos to @ra1028)

Miscellaneous

1. New convenience initializer for Action that takes a ValidatingProperty as its state (#637, kudos to @Marcocanc)

4.0.0

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

Xcode 10 Support

1. Swift 4.2 and Xcode 10 support (#644, kudos to @ikesyo)

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 @ra1028)

Changes: <~ Bindings

1. <~ bindings now works with optional left-hand-side operands. (#642, kudos to @andersio and @Ankit-Aggarwal)

   let nilTarget: BindingTarget<Int>? = nil
   
   // This is now a valid binding. Previously required manual
   // unwrapping in ReactiveSwift 3.x.
   nilTarget <~ notifications.map { $0.count }

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. When unfair locks from libplatform are unavailable, ReactiveSwift now fallbacks to error checking Pthread mutexes instead of the default. Mitigations regarding issues with pthread_mutex_trylock have also been applied. (#654, kudos to @andersio)
2. Lifetime may now be manually ended using Lifetime.Token.dispose(), in addition to the existing when-token-deinitializes semantic. (#641, kudos to @andersio)
3. Bag may now be initialised with a sequence of elements. (#609, kudos to @ra1028)
4. Non-class types may now conform to ReactiveExtensionProvider. (#636, kudos to @ra1028)
5. Fix some documentation errors about Carthage usage (#655)
6. [CocoaPods] CocoaPods 1.4.0 is the minimum required version. (#651, kudos to @ikesyo)
