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);

Full Changelog: 1.7.1...1.7.2

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.

• Infrastructure: Add docs for testing StackAction's case path subscript (thanks @lukeredpath, #2704).

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).
