0.50.0

What's Changed

• Added: @BindingState (renamed from @BindableState in this release) now conditionally conforms to Sendable (thanks @jshier, #1834).

• Added: SwiftUI Transaction helper APIs, including Effect.transaction, ViewStore.send(_:transaction:), and Effect.run { send in send(_:transaction:) } (thanks @drucelweisse, #1824).

• Added: Store.init now takes a prepareDependencies block, for preparing the initial dependencies of a store (TestStore introduced a similar API earlier) (#1844).

• Added: Effect.send has been introduced as a new version of Effect.init(value:) (#1859). Effect.init(value:) has been soft-deprecated and will be hard-deprecated soon, so prefer using Effect.send to synchronously feed actions back into the system.

• Changed: The @BindableState property wrapper has been renamed to @BindingState (#1855).

• Changed: TestStore ergonomics have been improved to better surface when APIs are unavailable due to lack of an Equatable conformance (#1857).

• Changed: Alert modifiers now use @StateObject instead of @ObservedObject in iOS 15 and higher (#1860).

• Changed: Reducer builders have been rewritten to be more performant and to prepare for forthcoming Swift 5.8 changes (#1863). If you notice any regressions in your app's reducer builders, please let us know.

• Changed: The Composable Architecture has been updated to depend on SwiftUI Navigation 0.6.0 (#1865).

  Warning: This upgrade contains breaking changes that mostly do not affect the Composable Architecture, with the exception of its UIKit alert helper tools, which will now require you to handle a nil alert action for dismissal/cancel buttons with no action attached.

• Fixed: #1802 introduced a slight regression in view store binding animation behavior, so it was reverted back to the original behavior (#1845).

• Fixed: Effect is now hard deprecated as planned (thanks @kalupas226, #1822).

• Fixed: The Composable Architecture now explicitly depends on Ordered Collections, rather than implicitly via its transitive dependency on Identified Collections (thanks @kalupas226, #1828).

• Fixed: TestStore.receive methods that take predicates and case paths no longer require Action equatability (#1856).

• Infrastructure: Removed and updated a few deprecated, flakey tests (#1816).

• Infrastructure: Added UI test to catch SwiftUI regressions (#1815; thanks @tgrapperon in #1819).

• Infrastructure: Doc fixes (thanks @brennobemoura, #1843).

• Infrastructure: Document testing gotchas (#1854).
