6.0.0 RC1

RxSwift 6.0.0 RC1

This is the first Release Candidate of RxSwift 6.

Note: RxSwift 6 supports Xcode 12 and Swift 5.3 and has a minimum deployment target of iOS 9.

• All ReactiveCompatible objects (.rx namespace) get Binders for all properties for free using @dynamicMemberLookup.
• New Infallible object which is identical to Observable with the guarantee of never failing.
• Add variadic drive() and emit() to multiple observers and relays.
• New decode(type:decoder:) operator for ObsrvableTypes of Data.
• SingleEvent is now simply Result<Element, Swift.Error> and methods changed accordingly (e.g. subscribe(onSuccess:onFailure:)).
• Add ReplayRelay.
• Add distinctUntilChanged(at keyPath:).
• Add UIApplication Reactive extensions .
• Rename catchError(_:) to catch(_:).
• Rename catchErrorJustReturn(_:) to catchAndReturn(_:).
• Rename elementAt(_:) to element(at:).
• Rename retryWhen(_:) to retry(when:).
• Rename takeUntil(_:) to take(until:) and takeUntil(behavior:_:) to take(until:behavior:).
• Rename takeWhile(_:) to take(while:) and takeWhile(behavior:_:) to take(while:behavior:).
• Rename take(_:) duration overload to take(for:) (e.g. take(for: .seconds(3))).
• Rename skipWhile(_:) to skip(while:).
• Rename takeUntil(_:) to take(until:).
• Rename observeOn and subscribeOn to observe(on:) and subscribe(on:).
• ignoreElements() now returns Observable<Never>.
• Make SharedSequence conform to ObservableConvertibleType.
• Add onDisposed to Maybe, Completable and Single.
• Unify and optimize swizzling extensions into a single one.
• Add DisposeBag function builder to allow easy comma-less initialization of a DisposeBag.
• Advance support of xcframeworks by enabling BUILD_LIBRARY_FOR_DISTRIBUTION and cleaning up.
• Many, many, many quality of life bugs and fixes.

Catalyst.1

This update is mandatory if you want to use RxSwift in Xcode 11.4 / Swift 5.2 on macOS.

• Make NSTextView not weak for Swift 5.2 and up. #2125
• Add WKWebView navigation delegate reactive extensions. #2144

Note:

• The pre-built Carthage binary was built using Xcode 11.4 / Swift 5.2
• We no longer guarantee support for Xcode 10.x. Maintaining these is counter-intuitive as they're over a year old and are ridden with bugs.

Other improvements and additions can be found in the project's CHANGELOG.md

Note:

The pre-built Carthage binary was built using Xcode 11.4.1 / Swift 5.2.2

Catalyst

This release removes UIWebView Reactive Extensions due to Apple's hard deprecation, starting April 2020 which also allows RxSwift to be used in Catalyst apps. #2062

Other improvements and additions can be found in the project's CHANGELOG.md

Note:

The pre-built Carthage binary was built using Xcode 11.3.1 / Swift 5.1.3

ShaiTheBravest

• Reverts Carthage integration from using static to dynamic libraries. #1960

NOTE: This release is only relevant to Carthage users (#1960), there are no code changes between RxSwift 5.0.0 and 5.0.1.

ShaiTheBrave

RxSwift 5 is a mostly source-compatible release targeting the Swift 5 compiler.

Xcode 10.2 is the minimum supported version (or Swift 5 on Linux).

If you're using Xcode 10.1 and below, please use RxSwift 4.5.

• Relays have been moved to a separate framework - RxRelay, and can be used without RxCocoa. #1924
• TimeInterval has been deprecated in favor of DispatchTimeInterval. For example - throttle(1.2) would change to throttle(.milliseconds(1200)), while throttle(3) would change to throttle(.seconds(3)). #1472
• Variable is now entirely deprecated. #1922
• do now provides additional "after" closures. For example, do(onNext:) and do(afterNext:). #1898
• bind(to:) now supports multiple observers (e.g. bind(to: observer1, observer2)). #1702
• Changes the return type of ObservableType.toArray to Single. #1923
• Adds compactMap. #1925
• Deprecate Completable.merge in favor of Completable.zip. #1929 #1931
• RxSwift can be built as a Static Library using Carthage 0.33 and up. #1940

Anomalies

• SubjectType.SubjectObserverType has been renamed to SubjectType.Observer. #1950
• The S associated type has been renamed to Subject where applicable. #1950
• The S generic constraint on SharedSequence has been renamed to SharingStrategy. #1951
• The E associated type on ObservableConvertibleType and ObserverType have been renamed to Element. #1945
• The C and S associated types have been renamed to Collection and Sequence accordingly. #1949
• Renamed ElementType associatedtype to Element. #1945
• Renamed TraitType associatedtype to Trait. #1945
• Make RxMutableBox supported on Linux in Swift 5. #1917
• Fix incorrect assignment to Thread.threadDictionary on Linux. #1912
• combineLatest of an empty array now completes immediately. #1879
• Add resultsSelector missing closure labels for some overloads of combineLatest & zip.

[4,5]

• Compatibility with Xcode 10.2.
• Adds missing UISearchBar.setDelegate().

Atomic.2

4.4.2

• Adds UIView.rx.backgroundColor Binder. #1888

Anomalies

• Fix multiple disposes on ScheduledDisposables. #1892
• Fix DelegateProxy main thread validation. #1882
• Bring back the first operator to ObservableType. #1886

Atomic.1

• Adds takeUntil(_ behavior:predicate:).

Anomalies

• Fixes problems with RxAtomic and thread sanitizer. #1853
• Fixes problem with passing 0 count to Observable.range. #1870
• Fixes Swift 5.0 warnings. #1859
• Fixes problem with RxCocoa and DISABLE_SWIZZLING flag. #1805
• Internal cleanups:
  • Unused code deletions.
  • Adds SwiftLint.
  • Removes legacy Swift 3.0 conditional compilation flags.

Atomic

This relase introduces new framework RxAtomic that enables using C11 atomic primities in RxSwift as a replacement for deprecated OSAtomic* functions.
Carthage users will probably need to include this framework manually.

• Updates deprecated OSAtomic* primitives to use C11 atomic primitives.
• Adds Event, SingleEvent, MaybeEvent and Recorded conditional conformance to Equatable where their Element is equatable on RXTest for clients that are using Swift >= 4.1.
• Adds string to NSTextView.
• Consolidates per platform frameworks to multi-platform frameworks.
• Xcode 10.1 compatible.

Anomalies

• Fixes problem with canceling events scheduled on serial scheduler through observeOn operator. #1778
• Fixes problem with UISearchBar.text property not triggering update when cancel button is tapped. #1714
• Updates watchos minimum target to 3.0. #1752

RotWeiß.1

Anomalies

• Fixes issues with CocoaPods and Swift 4.2 version.
