AsyncExtensions
The AsyncExtensions target is a growing collection of useful functions and classes that take advantage of Swift's new Concurrency features.
The AsyncExtensions package also inlcudes the AsyncTestExtensions target, which contains async-friendly wrappers around XCTest assertions.
AsyncExtensions includes
AsyncInputStream: A convenient wrapper aroundInputStreamallowing for simple, type-safe access to stream data.CombineAsyncStream: A backported version ofAsyncPublisher, which creates anAsyncStreamfrom a Combine Publisher and is only supported on iOS 15+.Future: A thread-safe implemention of a future that is useful when briding traditional Swift code with code employing Swift Concurrency.Sequence.asyncMap()andSequence.concurrentMap(): Extensions allowing for applying async transformations toSequence.TimeoutError: A simple error intending to represent a timeout. Modelled afterCancellationError.
AsyncTestExtensions includes
AssertEqual()AssertEqualEventually()AssertTrue()AssertTrueEventually()AssertFalse()AssertNil()AssertNotNil()AssertThrowsError()AssertNoThrow()
