Full Changelog: 1.8.0...1.8.1

1.8.0

What's Changed

See Migrating to 1.8 for more details.

• Added: New @Reducer macro features (#2795).

  The @Reducer macro has been enhanced to streamline usage and simplify some common patterns:

  • When left undefined, the @Reducer will now define default implementations of State, Action, and body. This means stubbing a feature is as simple as @Reducer struct Feature {}.

  • @Reducer can now be used with enums to simplify the boilerplate associated with "destination" and "path" reducers.

  See the 1.8 migration guide for more information on how to use these APIs.

• Fixed: Propagate @ViewAction macro availability (#2785).

• Fixed: Properly tag nested observable enums so that changes to non-observable cases are better observed (#2786).

• Infrastructure: Fix typo in migration guide 1.6 (thanks @takehilo, #2779); better document explicit id with scoped ForEach (#2784); Fix typo in the 1.7 migration guide (thanks @yaslab, #2780; thanks @Ryu0118, #2790);

1.7.2

What's Changed

• Fixed: A visionOS build regression introduced in 1.7.1 has been fixed (thanks @peterbohac, #2746).

1.7.1

What's Changed

• Fixed: The Composable Architecture's SwiftUI Binding helpers should better preserve SwiftUI animation and transaction information (#2740). Previously, animations could be lost in certain situations.
• Fixed: @ObservableState now supports the package access modifier (thanks @nnsnodnb, #2741).
• Deprecated: Reducer.onChange(of:removeDuplicates:) has been deprecated (#2744). The removeDuplicates argument put strain on the compiler that could cause reducers to not compile in time. Migration strategy: use an explicit wrapper type that is Equatable, instead.
• Infrastructure: Migrating to 1.7 fixes (thanks @acosmicflamingo, #2732; thanks @bricklife, #2736; thanks @zvona031, #2738; thanks @shgew; #2743); README fix (thanks @yimajo, #2734).

1.7.0

What's Changed

See Migrating to 1.7 for more details.

• Added: Observation support (#2593), which both streamlines and soft-deprecates many concepts in the Composable Architecture. See the 1.7 migration guide for more information on how to apply these updates to your applications.
• Infrastructure: Add CI for Swift 5.7.1 (#2701).
• Infrastructure: Add docs for testing StackAction's case path subscript (thanks @lukeredpath, #2704).

• Infrastructure: Fixed TestStore.assert docs (#2720).
• Infrastructure: Use XCTExpectFailure from XCTestDynamicOverlay (#2721).

• Infrastructure: Fixed concurrency docs (thanks @hmhv, #2726).
• Infrastructure: Fixed composing features tutorial (thanks @bricklife, #2698; thanks @Kyome22, #2727).
• Infrastructure: Fixed 1.7 migration guide (thanks @Ryu0118, #2731).

Full Changelog: 1.6.0...1.7.0

1.6.0

What's Changed

See Migrating to 1.6 for more details.

• Added: TestStore.receive(\.action, payload) for asserting against the payload of an action without requiring the action itself be Equatable (#2669; #2691)
• Fixed: It was possible for ViewStores to ping their objectWillChange publisher during a body computation, triggering a SwiftUI warning. This has been fixed (#2688).
• Fixed: @Reducer macro no longer automatically applies @CasePathable macro to enums with explicit conformance (thanks @scogeo, #2685).
• Fixed: The prepareDependencies closure is now only performed a single time when creating a store, not every single time an action is received (#2695).
• Fixed: A retain cycle in PresentationModifier has been fixed (#2697).
• Performance: Clean up parent/child store invalidation checks (#2674).
• Infrastructure: Fix package build in 5.7 for SPI (#2675; thanks @finestructure, #2679).
• Infrastructure: Typo fix (thanks @tomokisun, #2678).
• Infrastructure: Add documentation around new store scoping characteristics (#2676).
• Infrastructure: Prevent unnecessary tutorial diffs (thanks @bricklife, #2692).
• Infrastructure: Tutorial fixes (#2693).
• Infrastructure : Clean up shared state case study (#2696).

1.5.6

What's Changed

Important

While this release contains no additions or breaking changes to the Composable Architecture's APIs, the Store.scope operation has been significantly refactored for performance. While we have vetted these changes in our own test suites and applications, and have worked with members of the community to test these changes before this release, please thoroughly test the view layer of your applications after upgrading to this version, and before releasing your application to production.

See #2664 for more details on the change.

• Performance: Overhaul store scope communication (#2664).
• Infrastructure: Update sample code to use the @DependencyClient macro (#2653).
• Infrastructure: Update migration guide with more information about applying @CasePathable to enums (#2672).
• Infrastructure: Add basics of composition to the "essentials" tutorial (#2659).

Full Changelog: 1.5.5...1.5.6

1.5.5

What's Changed

• Fixed: A retain cycle fix in 1.5.4 could lead to regressions where stores can deinitialize before actions make it back into the system. This has been reverted and will have to be addressed in the future (#2648).

Full Changelog: 1.5.4...1.5.5

1.5.4

What's Changed

• Fixed: Archives should no longer fail due to BindableAction symbols (thanks @rhysm94, #2641).
• Fixed: Stores no longer leak for the duration of an async effect. Instead, they will automatically cancel their in-flight effects when they deinitialize (#2643).
• Infrastructure: Improve docs for sharing logic in parent and child features (#2638).
• Infrastructure: Update test cases to use case key paths (thanks @yimajo, #2637).
• Infrastructure: Fix tutorial code diffs (#2642).
