0.6.0

• Added: SwiftUI alert and action sheet helpers via AlertState and ActionSheetState.
• Changed: ViewStore no longer uses @Published to coordinate its state with ObservableObject.

0.5.0

• Added: ComposableCoreMotion, a micro library for integrating the Composable Architecture with Core Motion.
• Improved: Store.send now prints the action sent in its assertion failure for better debugging (thanks @ollitapa).
• Changed: Reducer.debug now uses Publishers.MergeMany instead of Publishers.Concatenate to avoid a Combine bug that results in a memory leak.
• Infrastructure: document rxswift-composable-architecture (thanks @dannyhertz), move ViewStore.swift into the root directory (thanks @dannyhertz), reorganize VoiceMemos demo for readability.

0.4.0

• Added: ComposableCoreLocation types now conform to Codable (thanks @alskipp).
• Added: Reducer debug methods now take an actionFormat parameter.
• Changed: depend on CombineSchedulers instead of vendoring AnyScheduler and TestScheduler. The library contains several bug fixes over the code that was included in 0.3.0.
• Fixed: use subscribe method over receive(subscriber:), per Apple documentation (thanks @asiliuk).
• Improved: ComposableCoreLocation delegate ergonomics (thanks @klundberg).
• Optimized: signposts should be a little more performant now.
• Optimized: store.send no longer recursively processes effects and instead processes them in a while loop, avoiding stack issues (thanks @klop).
• Optimized: IfLetStore view content types been simplified.
• Infrastructure: link to ReactiveSwift fork (thanks @mluisbrown).
• Infrastructure: encapsulate Publishers.Create and AnyPublisher.init(_:) (thanks @kaandedeoglu).
• Infrastructure: clean up tests around cancellation (thanks @klop).
• Infrastructure: added a new web socket case study.
• Infrastructure: fixed voice memo assertion failure.

0.3.0

• Added: reducers can now be instrumented with signposts using the signposts higher-order reducer.
• Changed: debugged reducers will now omit printing state when no state changes.
• Bug fixed: several bugs around automatically synthesized mutating methods on IdentifiedArray, including replaceSubrange and sort (thanks @peterkovacs).
• Bug fixed: chaining multiple cancellable calls onto a single effect with the same identifier no longer crashes.
• Infrastructure: better support for iPad in the demo apps.
• Infrastructure: cleaned up location manager app annotation behavior (thanks @kaandedeoglu).

0.2.0

• Added: ComposableCoreLocation, a micro library for interfacing the Composable Architecture with Core Location.

0.1.5

• Added: a TestStore.assert method that takes an array of steps (thanks @pteasima).
• Changed: misusing identified array's id-based subscript (attempting to update an element not in the array, or attempting to nil out an element) will now crash with a helpful error message in development.
• Changed: WithViewStore.debug logic is now a no-op in release mode.
• Changed: Reducer.debug and WithViewStore.debug can now omit the prefix argument name to more closely align with Publisher.print.
• Bug fixed: test schedulers now properly order concurrent work items.
• Bug fixed: debug output will no longer overflow on infinitely recursive references.
• Infrastructure: README fixes (thanks @OfftheCode), documentation fixes (thanks @johankool), new location manager demo, animation case study fixed for dark mode.

0.1.4

• Added: IdentifiedArray.remove(id:) method for removing elements by identifier.
• Added: Reducer.combined(with:) method for combining reducers using dot-chaining (thanks @alexito4).
• Added: Reducer.run method for invoking the reducer in a more ergonomic fashion than callAsFunction in Swift 5.1.
• Changed: optimized test support code to dynamically load XCTest just once per test process (rather than once per assertion failure).
• Changed: IdentifiedArray's id-based subscript no longer removes elements from the array when passed nil. Use remove(id:) instead.
• Changed: CasePath is no longer vendored. It is instead included as an SPM dependency.
• Changed: Effect.async has been renamed to Effect.run.
• Changed: Effect.sync has been renamed to Effect.catching.
• Bug fixed: TestScheduler now always performs/schedules simultaneous work by earliest-scheduled.
• Infrastructure: added binding-based animation demo to case studies.
• Infrastructure: add Swift forum to README.
• Infrastructure: fixed typo in IfLetStore documentation (thanks @jasdev).

0.1.3

Breaking changes:

• ComposableArchitecture is no longer a dynamic library. To upgrade:
  • You will need to reintegrate the library into your application. You can reintegrate by removing and re-adding the library to your application or shared framework target.
  • If you include ComposableArchitecture in more than one target in your project, you must move it to a single, dynamic framework, instead. Then this framework is what you can share among your app, framework, and test targets. For an example, check out the Tic-Tac-Toe demo application, which has been modularized and integrates ComposableArchitecture in this fashion.
• ComposableArchitectureTestSupport has been removed and TestStore has moved into ComposableArchitecture. To upgrade:
  • Change import ComposableArchitectureTestSupport to import ComposableArchitecture in your tests.

Other changes:

• Added: stateless and actionless transformations to Store to more easily derive stores that should only send actions or only read state.
• Changed: IfLetStore no longer wraps its content in a Group.
• Bug fixed: TestStore's assert no longer crashes when working with empty state structs (thanks @jlainog).
• Infrastructure: decluttered CI output using xcodebuild -quiet (thanks @tarjamorgado).
• Infrastructure: demos now build in Xcode 11.3.1.

0.1.2

• Bug fixed: Xcode previews should no longer always crash during compilation.
• Infrastructure: simpler Tic-Tac-Toe winning condition logic (thanks @thomasmarsh).

0.1.1

• Added: TestStore now has scope methods that mirrors its Store counterpart for testing view store transformations.
• Removed: TestStore no longer has an initializer that takes state and action transformations. Use scope instead.
• Changed: identified array's id-based subscript now takes an explicit id parameter name. This avoids ambiguity when subscripting into an array of Int-identified elements.
• Bug fixed: annotating reducers with debug() no longer breaks them in release builds (thanks @tulushev).
• Bug fixed: nil-ing out an element of an identified array no longer puts it in an invalid state.
• Bug fixed: removing more than one element of an identified array via index set should no longer remove any incorrect elements or crash.
• Improved: messaging for out-of-bounds forEach errors (thanks @ryantstone for bringing up the issue).
• Improved: documentation (thanks @alohaglenn, @ReadmeCritic 😉, @natemann).
