Combine Publishers | Episode 45

Publisher provides data when available and upon request. Publisher without subscriber does not provide any data. 1) Just: Provides single value and completes. 2) Future: Closure that resolves to single output value or failure completion. 3) Deferred: Wraps creation of any publisher and only creates it when a subscriber is present. 4) AnyPublisher: Publisher is a protocol. AnyPublisher, on the other hand, is a concrete implementation of the Publisher protocol. It does not have any notable properties of its own but instead forwards the elements and completion values from its upstream publisher. AnyPublisher is used to wrap a publisher whose specific type details we wish to keep hidden or not expose. To expose an instance of AnyPublisher to a downstream subscriber, we can utilize the eraseToAnyPublisher() method. 5) Empty: Only used for task completion. Publisher that never publishes any values and optionally finishes immediately. We can create Never publisher, one which never sends values and never finishes or fails with Empty(completeImmediately: false) 6) Sequence - Publish sequence of elements. 7) Fail - Teminates publishing with specified error. 8) Record - Publishers that allows for recording series of input and completion, for later playback to each subscriber. 9) @Published - Property wrapper that adds a combine publisher to any property.
