1.9.0

• Xcode 12.4 compatibility

1.8.4

• Fix compilation errors in Xcode 11.4 beta
• Use Swift.Result instead of custom result implementation
• Update sample to match readme.

1.8.3

• Fix race conditions for iOS 13 for Signal and cleanup CallbackState
• Add new combiner driven(by:) that makes a ReadSignal emit its latest readable values when the given "driver" signal fires events. The combined signal will derive its signal kind from the driver, but without write access.

1.8.2

• Fix the traitCollectionWithFallback behaviour on iOS 13 to return the view's predicted traits and prior iOS 13 to respect the key window's traits before falling back to the main screen traits.

1.8.1

• Added signal transformations contains(where:) and allSatisfy(where:) as wrappers for boolean reduce() transforms.
• Changed reduce() implementation to consider initial values when performed on readable signals.

1.8

• Added deallocSignal(for:) and NSObject.deallocSignal for listen on deallocation of objects.
• Added signal transformation with(weak:) as a convenience helper for breaking retain cycles.

1.7

• Migration to Swift 5.

1.6

• Addition: Make Callbacker conform to SignalProvider.

1.5.2

• Bugfix: Make sure shared() updates its last value before calling out to get correct results in case of recursion.

1.5.1

• Update combineLatest to no longer allow mixing of plain and readable signals as for the returned signal to guarantee to be readable all provided signals must as be readable as well. This is technically a breaking of the API, but as the existing implementation is broken and might result in run-time crashes, this change can be considered as a bug-fix.

1.5

• Added new Future and Signal delay alternatives that accepts a closure that returns the delay based on the value allow variable delays.

1.4.2

• Fixed a bug with some of Future's repeat methods where the delay delayBetweenRepetitions was added after the last repetition as well.
• Fixed bug where the predicate passed to onResultRepeat was not always scheduled correctly.

1.4.1

• Fixes a problem where onErrorRepeat would not respect the specified delay interval.
• Fixed issues with tvOS support.
• Updates some transforms such as toVoid() to schedule on .none instead of .current so these transforms won't cause a re-schedule.

1.4

• Updated the Signal.flatMapLatest() transformation to allow more flexible mixing of signal types between self and the signal returned from transform.
• Added Signal.toogle() method for read-write boolean signals.
• Added didWrite() transformations to read-write signals.
• Added UIControl valueChanged that will signal with the latest value when the control event .valueChanged is signaled.

1.3.1

• Bugfix: Updated Future.abort(forFutures:) to more correctly handle repetition.

1.3

• Added versions of bindTo() that can bind a non optional to an optional value.
• Added enable() to Enablable similar as disable().
• Added more defaulted parameters to Scheduler.init for dispatch queues.
• Fixes a crash on Swift 4.2 when immediately (on the same line) modifying a ReadWriteSignal's value.
• Added Scheduler perform helper.
• Added signal withLatestFrom transformation.

1.2.1

• Conditionally conform Either to Hashable when Left and Right conforms to Hashable.
• Conforms UISlider to SignalProvider.

1.2

• Added NSManagedObjectContext.scheduler property for scheduling work on managed object contexts when CoreData is available.

1.1

• Added DisposeBag.hold() convenience method for holding a reference to an object.
• Added UITextField delegates for shouldEndEditing and shouldReturnl
• Added UITextField.isEditingSignal signal.
• Added UIView.install() for installing gesture recognizers.
• Added UIView signals for displaying editing menu for copy, cut and paste.
• Added orientationSignal that will signal on orientation changes.
• Added UIRefreshControl animate() and refersh() helpers.
• Added disableActiveEventListeners() helper
