Extensions for ReactiveCocoa that may not fit in the core framework.
All Signal operators can also be lifted toSignalProducer.
Applies transform to values from signal with non-nil results unwrapped and forwared on the returned signal. This is equivalent to map { … } |> filter { $0 != nil } |> map { $0! } but without creating extra intermediate signals.
func filterMap<T, U, E>(transform: T -> U?)(signal: Signal<T, E>) -> Signal<U, E>Wraps a signal in a version that drops Error events. By default errors are replaced with a Completed event but Interrupted can also be specified as replacement.
func ignoreError<T, E>(signal: Signal<T, E>) -> Signal<T, NoError>
func ignoreError<T, E>(#replacement: Event<T, NoError>)(signal: Signal<T, E>) -> Signal<T, NoError>Flattens batches of elements sent on signal into each individual element. The inverse of collect.
func uncollect<S: SequenceType, E>(signal: Signal<S, E>) -> Signal<S.Generator.Element, E>Operators specific to SignalProducer.
Partitions values from producer into new producer groups based on the key returned from grouping. Termination events on the original producer are forwarded to each inner producer group.
func groupBy<K: Hashable, T, E>(grouping: T -> K)(producer: SignalProducer<T, E>)
-> SignalProducer<(K, SignalProducer<T, E>), E>Rex is released under the MIT license
