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).

Full Changelog: 1.5.3...1.5.4

1.5.3

What's Changed

• Fixed: Don't force-unwrap state from invalidated optional stores when replaying parent state updates (#2633). This force-unwrap could affect IfLetStore views.

Full Changelog: 1.5.2...1.5.3

1.5.2

What's Changed

• Performance: cache more child stores and avoid extra copies of child/presented state (#2627).
• Infrastructure: 1.5 migration guide updates (#2615); link to observation beta in README (#2616).

Full Changelog: 1.5.1...1.5.2

1.5.1

What's Changed

• Fixed: BindingAction's case key path extraction was broken, which could lead to actions received through effects to not be testable, .e.g \.binding.$text would fail to match .binding(.set(\.$text, "Blob")). This has been fixed (#2600).
• Fixed: Store caching introduced in 1.5 could lead to a regression in which a child store becomes "detached" when an uncached parent is deinitialized. This has been fixed by only caching child stores when its parents are cached (#2605).
• Fixed: NavigationStackStore's internal use of @StateObject could lead to broken navigation. By using an @ObservedObject instead we now avoid this bug (#2599).
• Infrastructure: Fixed typo in 1.5 migration guide (thanks @Ryu0118, #2595; thanks @yimajo, #2606); update documentation links in README (thanks @woxtu, #2598);

Full Changelog: 1.5.0...1.5.1

1.5.0

What's Changed

See Migrating to 1.5 for more details.

• Added: A new Store.scope method that takes a state key path and action case key path (#2527). This method uses the hashability of key paths to cache scoped child stores in the parent, improving the performance of store scoping, especially when SwiftUI views are recomputed.

  See the migration guide for more info.

• Added: DependenciesMacros is now automatically exported, making @DependencyClient available by default when importing the Composable Architecture (thanks @tgrapperon, #2586).

• Infrastructure: Fixed links in the migration guide (thanks @woxtu, #2578).

Full Changelog: 1.4.2...1.5.0

1.4.2

What's Changed

• Fixed: swift-case-paths is now correctly pinned from 1.1.0, which should avoid some SPM resolution issues (thanks @bdolewski-intellias, #2577).

Full Changelog: 1.4.1...1.4.2

1.4.1

What's Changed

• Fixed: A regression in Reducer.forEach was introduced in 1.4 that broke compilation in some cases, notably in the TCACoordinators library. This regression has been corrected (thanks @rhysm94, #2570).
• Infrastructure: Updated Japanese and Korean README translations (thanks @Achoo-kr, #2563, #2562).
• Infrastructure: Fixed documentation links (thanks @johankool, #2566, #2576); fixed migration guide typos (thanks @kalupas226, #2569; @woxtu, #2575; @Ryu0118, #2574).
• Infrastructure: Clean up case study (thanks @mike123789-dev, #2567).

1.4.0

What's Changed

See Migrating to 1.4 for more details.

• Added: The @Reducer macro (#2553). See the migration guide for more details.

• Fixed: Silenced a SwiftUI sendability warning (#2540).
• Fixed: Alert and confirmation dialog helpers now use Text(verbatim: "") to avoid localization warnings (#2541).
• Fixed: Reducer.onChange no longer requires an Equatable conformance (thanks @lukaskubanek, #2545).
• Infrastructure: Updated Swift compiler version to 5.7.1 to follow Apple's policy (thanks @jaesung-0o0, #2549).
• Fixed: Short circuit equatability of ordered sets when counts don't match (#2556).
• Infrastructure: Added previews to integration test cases by (#2551)
