Tests/AblyChatTests/Mocks/MockRoomLifecycleManagerFactory.swift (2)

: Consider adding documentation for testing scenariosWhile the initialization is straightforward, adding documentation about common testing scenarios and usage examples would improve the mock's usability.
+/// A mock factory for creating RoomLifecycleManager instances in tests. +/// Usage example: +/// ``` +/// let mockManager = MockRoomLifecycleManager() +/// let factory = MockRoomLifecycleManagerFactory(manager: mockManager) +/// ``` init(manager: MockRoomLifecycleManager = .init()) { self.manager = manager }
1-13
: Consider adding verification methods for testingTo enhance testability, consider adding methods to verify if the factory was called with expected parameters.
actor MockRoomLifecycleManagerFactory: RoomLifecycleManagerFactory { private let manager: MockRoomLifecycleManager + private var createManagerCalls: [(contributors: [DefaultRoomLifecycleContributor], logger: any InternalLogger)] = [] init(manager: MockRoomLifecycleManager = .init()) { self.manager = manager } func createManager(contributors: [DefaultRoomLifecycleContributor], logger: any InternalLogger) async -> MockRoomLifecycleManager { + createManagerCalls.append((contributors: contributors, logger: logger)) manager } + + /// Returns the number of times createManager was called + func createManagerCallCount() async -> Int { + createManagerCalls.count + } + + /// Returns the parameters used in createManager calls + func getCreateManagerCalls() async -> [(contributors: [DefaultRoomLifecycleContributor], logger: any InternalLogger)] { + createManagerCalls + } }Sources/AblyChat/SimpleClock.swift (1)
12-14
: Consider adding bounds checking for extreme time intervalsWhile the current implementation works well for typical use cases, consider adding validation for extreme time intervals to prevent potential overflow when converting to nanoseconds.
internal func sleep(timeInterval: TimeInterval) async throws { + guard timeInterval >= 0, timeInterval <= TimeInterval(UInt64.max) / Double(NSEC_PER_SEC) else { + throw SimpleClock.Error.invalidTimeInterval + } try await Task.sleep(nanoseconds: UInt64(timeInterval * Double(NSEC_PER_SEC))) }Add this error type above the protocol:
extension SimpleClock { enum Error: Swift.Error { case invalidTimeInterval } }Sources/AblyChat/RoomFeature.swift (1)
18-21
: Consider enhancing error handling for unimplemented featuresWhile
fatalError
is appropriate for development, consider these improvements for better debugging and maintenance:case .typing, .reactions, .presence, .occupancy: // We'll add these, with reference to the relevant spec points, as we implement these features - fatalError("Don't know channel name suffix for room feature \(self)") + // TODO: [ECO-4982] Implement channel name suffixes for remaining features + assertionFailure("Channel name suffix not implemented for room feature \(self)") + return "unimplemented_\(self)"This change:
- Links the TODO to the current ticket
- Uses
assertionFailure
which fails in debug but allows release builds- Returns a fallback value that makes debugging easier
Tests/AblyChatTests/DefaultChatClientTests.swift (1)
25-27
: LGTM! Consider adding tests for custom lifecycle manager factories.The type assertion change correctly reflects the new generic implementation of
DefaultRooms
. The test properly verifies both the type casting and property preservation.Consider adding a test case that verifies
DefaultRooms
works with custom lifecycle manager factories to ensure the generic implementation is truly flexible. Here's a suggested test:@Test func rooms_withCustomLifecycleManagerFactory() throws { // Given: A custom lifecycle manager factory struct CustomFactory: RoomLifecycleManagerFactory { func create(for room: Room) -> RoomLifecycleManager { return DefaultRoomLifecycleManager(room: room) } } // And: An instance of DefaultChatClient configured with the custom factory let realtime = MockRealtime.create() let options = ClientOptions() let client = DefaultChatClient( realtime: realtime, clientOptions: options, lifecycleManagerFactory: CustomFactory() ) // Then: Its `rooms` property returns an instance of DefaultRooms with the custom factory let rooms = client.rooms let defaultRooms = try #require(rooms as? DefaultRooms<CustomFactory>) #expect(defaultRooms.testsOnly_realtime === realtime) #expect(defaultRooms.clientOptions.isEqualForTestPurposes(options)) }Sources/AblyChat/DefaultRoomLifecycleContributor.swift (1)
1-48
: Consider enhancing error handling and state management.While the implementation is solid, consider these architectural improvements:
- Add state validation in the contributor to ensure operations are only performed in valid states
- Consider implementing retry logic for transient failures in channel operations
- Add telemetry/logging for better observability of lifecycle events
This aligns with the broader integration goals mentioned in ECO-4982 and would make the system more robust.
Sources/AblyChat/ChatClient.swift (1)
23-24
: Consider making the lifecycle manager factory configurableWhile the integration of the lifecycle manager aligns well with the PR objectives, creating the factory with default configuration might limit flexibility. Consider allowing the factory to be injected through
ClientOptions
or the initializer parameters.Here's a suggested approach:
public struct ClientOptions: Sendable { public var logHandler: LogHandler? public var logLevel: LogLevel? + public var roomLifecycleManagerFactory: RoomLifecycleManagerFactory? - public init(logHandler: (any LogHandler)? = nil, logLevel: LogLevel? = nil) { + public init( + logHandler: (any LogHandler)? = nil, + logLevel: LogLevel? = nil, + roomLifecycleManagerFactory: RoomLifecycleManagerFactory? = nil + ) { self.logHandler = logHandler self.logLevel = logLevel + self.roomLifecycleManagerFactory = roomLifecycleManagerFactory } } public actor DefaultChatClient: ChatClient { // ... public init(realtime: RealtimeClient, clientOptions: ClientOptions?) { self.realtime = realtime self.clientOptions = clientOptions ?? .init() logger = DefaultInternalLogger(logHandler: self.clientOptions.logHandler, logLevel: self.clientOptions.logLevel) - let roomLifecycleManagerFactory = DefaultRoomLifecycleManagerFactory() + let roomLifecycleManagerFactory = self.clientOptions.roomLifecycleManagerFactory ?? DefaultRoomLifecycleManagerFactory() rooms = DefaultRooms(realtime: realtime, clientOptions: self.clientOptions, logger: logger, lifecycleManagerFactory: roomLifecycleManagerFactory) } // ... }Tests/AblyChatTests/Mocks/MockRoomLifecycleManager.swift (2)
19-25
: Fix error message in fatalError.The error message mentions "performAttachOperation" but this is in the attach operation context.
- fatalError("In order to call performAttachOperation, attachResult must be passed to the initializer") + fatalError("In order to call performAttachOperation, attachResult must be passed to the initializer")
42-52
: LGTM! Consider weak references for long-lived tests.While the implementation is correct, consider using weak references if subscriptions might be long-lived in tests to prevent potential memory retention.
- private var subscriptions: [Subscription<RoomStatusChange>] = [] + private var subscriptions: [Weak<Subscription<RoomStatusChange>>] = []Tests/AblyChatTests/DefaultRoomsTests.swift (1)
13-13
: LGTM! Consider extracting common test setup.The addition of
lifecycleManagerFactory
parameter is correct and aligns with the integration objectives. However, since this initialization is repeated in all test methods, consider extracting it to a helper method or setup function to improve test maintainability.private func createDefaultRooms() -> DefaultRooms<MockRoomLifecycleManagerFactory> { let realtime = MockRealtime.create(channels: .init(channels: [ .init(name: "basketball::$chat::$chatMessages"), ])) return DefaultRooms( realtime: realtime, clientOptions: .init(), logger: TestLogger(), lifecycleManagerFactory: MockRoomLifecycleManagerFactory() ) }Sources/AblyChat/Rooms.swift (2)
9-9
: Consider decouplingDefaultRooms
fromDefaultRoomLifecycleContributor
for greater flexibilityThe generic constraint
LifecycleManagerFactory: RoomLifecycleManagerFactory<DefaultRoomLifecycleContributor>
tightly couplesDefaultRooms
withDefaultRoomLifecycleContributor
. If you plan to support different implementations ofRoomLifecycleContributor
in the future, consider abstracting this relationship. You can achieve this by:
- Making
RoomLifecycleManagerFactory
generic over theRoomLifecycleContributor
type.- Introducing an associated type in the
RoomLifecycleManagerFactory
protocol.This will enhance the modularity and reusability of your code.

56-58
: Provide a safe implementation for therelease
methodThe
release(roomID:)
method currently contains afatalError("Not yet implemented")
, which will crash the application if called. To prevent potential runtime crashes, consider providing a safe implementation or throwing a meaningful error to inform callers that the method is not yet available.Would you like assistance in implementing a placeholder for the
release
method that safely handles the unimplemented functionality?Sources/AblyChat/Room.swift (2)
80-83
: Consider including all required room features increateChannels
Currently,
createChannels
only includes themessages
feature. If other features likepresence
,reactions
,typing
, andoccupancy
are to be supported, consider including them in the channel creation to ensure they are initialized properly.
124-128
: Consider markingstatus
property asnonisolated
if accessed frequentlyIf the
status
property is accessed frequently and does not modify the actor's isolated state, consider marking it asnonisolated
to allow concurrent reads without actor hopping. Ensure thread safety if doing so.Tests/AblyChatTests/DefaultRoomTests.swift (5)
17-17
: Consider refactoring the initializer for better readabilityThe
DefaultRoom
initializer at line 17 has a long list of parameters, which can impact readability and maintainability. Consider refactoring by formatting the parameters across multiple lines or using a builder pattern if appropriate.Apply this diff to improve readability:
let room = try await DefaultRoom( realtime: realtime, chatAPI: ChatAPI(realtime: realtime), roomID: "basketball", options: .init(), logger: TestLogger(), lifecycleManagerFactory: MockRoomLifecycleManagerFactory() )
55-56
: Consider avoiding#expect
withawait
for better failure messagesUsing
#expect
withawait
in asynchronous tests may result in less informative failure messages, making debugging harder. Consider usingXCTAssertEqual
or otherXCTest
assertions that provide better diagnostic information.This suggestion is based on previous learning:
In Swift Testing, using
#expect
withawait
may result in less informative failure messages when debugging asynchronous tests.Apply this diff to improve the assertions:
- #expect(Result.areIdentical(result, managerAttachResult)) - #expect(await lifecycleManager.attachCallCount == 1) + XCTAssertTrue(Result.areIdentical(result, managerAttachResult)) + let callCount = await lifecycleManager.attachCallCount + XCTAssertEqual(callCount, 1)
91-92
: Consider avoiding#expect
withawait
for better failure messagesAs previously mentioned, using
#expect
with asynchronous code may lead to less helpful failure messages. Switching toXCTest
assertions can enhance debuggability.Apply this diff to improve the assertions:
- #expect(Result.areIdentical(result, managerDetachResult)) - #expect(await lifecycleManager.detachCallCount == 1) + XCTAssertTrue(Result.areIdentical(result, managerDetachResult)) + let callCount = await lifecycleManager.detachCallCount + XCTAssertEqual(callCount, 1)
114-114
: Consider avoiding#expect
withawait
for better failure messagesUsing
#expect
withawait
may result in less informative error messages. UsingXCTAssertEqual
can provide clearer insights when tests fail.Apply this diff to improve the assertion:
- #expect(await room.status == lifecycleManagerRoomStatus) + let status = await room.status + XCTAssertEqual(status, lifecycleManagerRoomStatus)
137-138
: Consider avoiding#expect
withawait
for better failure messagesAs with previous instances, replace
#expect
withXCTest
assertions to improve the clarity of failure messages in asynchronous tests.Apply this diff to improve the assertion:
- let roomStatusChange = try #require(await roomStatusSubscription.first { _ in true }) - #expect(roomStatusChange == managerStatusChange) + let roomStatusChange = try await roomStatusSubscription.first { _ in true } + XCTAssertEqual(roomStatusChange, managerStatusChange)Sources/AblyChat/RoomLifecycleManager.swift (10)
43-48
: Clarify theroomStatus
property access level andasync
usageThe
roomStatus
property is declared asasync
:var roomStatus: RoomStatus { get async }Since
RoomStatus
is likely a simple value type, consider whether accessing it needs to beasync
. If the property access doesn't involve asynchronous operations, removingasync
can simplify the interface and usage. Additionally, ensure that any conforming types handle thisasync
requirement appropriately.
50-58
: Specify generic constraints forRoomLifecycleManagerFactory
The
RoomLifecycleManagerFactory
protocol defines associated types without constraints:associatedtype Contributor: RoomLifecycleContributor associatedtype Manager: RoomLifecycleManagerConsider adding constraints to
Manager
to ensure it's associated with theContributor
type:associatedtype Manager: RoomLifecycleManager where Manager.Contributor == ContributorThis can help enforce consistency between the factory's contributor and the manager's contributor types, preventing potential type mismatches.
60-71
: InitializeDefaultRoomLifecycleManager
withoutawait
In
DefaultRoomLifecycleManagerFactory
, thecreateManager
function is marked asasync
, but the initialization doesn't perform any asynchronous operations:internal func createManager( contributors: [DefaultRoomLifecycleContributor], logger: InternalLogger ) async -> DefaultRoomLifecycleManager<DefaultRoomLifecycleContributor> { await .init( contributors: contributors, logger: logger, clock: DefaultSimpleClock() ) }Since the initializer is synchronous, consider removing the
async
keyword from both the function and initializer to simplify usage. Alternatively, if the initializer must be asynchronous, clarify the need toawait
it during initialization.
647-652
: Duplicate method definitions forperformAttachOperation
There are two definitions for
performAttachOperation
:internal func performAttachOperation() async throws { try await _performAttachOperation(forcingOperationID: nil) } internal func performAttachOperation(testsOnly_forcingOperationID forcedOperationID: UUID? = nil) async throws { try await _performAttachOperation(forcingOperationID: forcedOperationID) }Consider merging these into a single method with a default parameter:
internal func performAttachOperation(forcingOperationID: UUID? = nil) async throws { try await _performAttachOperation(forcingOperationID: forcingOperationID) }This reduces redundancy and simplifies the API. If the
testsOnly_
prefix is required for testing purposes, consider using conditional compilation directives to exclude test-specific code from production builds.
658-658
: Update Documentation Comment FormattingIn the documentation for
_performAttachOperation
, there's a minor formatting issue:/// - Parameters: /// - forcedOperationID: Allows tests to force the operation to have a given ID. In combination with the ``testsOnly_subscribeToOperationWaitEvents`` API, this allows tests to verify that one test-initiated operation is waiting for another test-initiated operation.Ensure there's an empty line after the documentation comment and before the method definition to improve readability and adhere to standard Swift documentation practices.
766-773
: Duplicate method definitions forperformDetachOperation
Similarly to
performAttachOperation
, there are two definitions forperformDetachOperation
:internal func performDetachOperation() async throws { try await _performDetachOperation(forcingOperationID: nil) } internal func performDetachOperation(testsOnly_forcingOperationID forcedOperationID: UUID? = nil) async throws { try await _performDetachOperation(forcingOperationID: forcedOperationID) }Consider merging these into a single method with a default parameter to reduce redundancy:
internal func performDetachOperation(forcingOperationID: UUID? = nil) async throws { try await _performDetachOperation(forcingOperationID: forcingOperationID) }
778-778
: Update Documentation Comment FormattingAs with the previous comment, in the documentation for
_performDetachOperation
, there is a formatting issue:/// - Parameters: /// - forcedOperationID: Allows tests to force the operation to have a given ID. In combination with the ``testsOnly_subscribeToOperationWaitEvents`` API, this allows tests to verify that one test-initiated operation is waiting for another test-initiated operation.Ensure there's an empty line between the documentation comment and the method definition for consistency and readability.

646-773
: Consider Extracting Common Operation LogicThe
performAttachOperation
andperformDetachOperation
methods have similar structures, including handling of operation IDs and waiting for operations to complete. Consider extracting common logic into a shared function or using generic methods to reduce code duplication and enhance maintainability.
Line range hint
43-773
: Review the Use of Force Unwrapping and Force TriesThroughout the code, particularly in the
waitForCompletionOfOperationWithID
method and other areas, force unwrapping and force tries are used:try! await clock.sleep(timeInterval: 1)Force unwrapping can lead to runtime crashes if not carefully managed. It's recommended to handle potential errors gracefully using do-catch blocks or propagating errors using
try
without the exclamation mark. This enhances the robustness of the code.

855-862
: Ensure Proper Task Cancellation HandlingIn the
bodyOfReleaseOperation
method, there's a TODO comment regarding task cancellation:// TODO: Make this not trap in the case where the Task is cancelled (as part of the broader https://github.com/ably-labs/ably-chat-swift/issues/29 for handling task cancellation)
Properly handling task cancellation is crucial to prevent unexpected behavior or resource leaks. Consider addressing this TODO by implementing cancellation checks and ensuring that your asynchronous operations respond appropriately to cancellations.
Would you like help implementing proper task cancellation handling in this area?

: LGTM: Good use of actor for thread-safe mock implementation
The actor designation ensures thread-safe access to the manager instance, which is particularly important when testing concurrent operations.

: Implementation looks good!
The DefaultSimpleClock
implementation correctly conforms to the SimpleClock
protocol and properly handles the time unit conversion for Task.sleep
. The use of final

: Verify the removal of channel name suffix for typing feature
The consolidation of cases suggests that the .typing
feature's channel name suffix implementation has been removed. Let's verify if this change is intentional and doesn't break existing functionality.
✅ Verification successful
The consolidation of typing feature is intentional and correct
The git history and codebase analysis reveals that this change is part of a planned restructuring where:
- The typing feature was previously implemented with a channel suffix "typingIndicators"
- The change is part of a broader integration of the room lifecycle manager (commit 03b31b3)
- The typing feature is still actively used in the codebase (Example/AblyChatExample/ContentView.swift shows typing subscription)

: Address Multiple TODO Comments Throughout the Code
There are several TODO comments indicating areas that need further attention or decisions:
- Handling unexpected contributor states after attach failure
- Deciding the right thing to do when state change events lack reasons
- Implementing asynchronous behavior as per the specification
- Determining correct wait times for retries
It's important to address these TODOs to ensure the code behaves as expected and meets the required specifications. Unresolved TODOs can lead to incomplete features or unexpected issues in production.
Would you like assistance in creating a plan to address these TODO items or opening GitHub issues to track them?

The attach/detach operations properly delegate to the lifecycle manager while maintaining the error handling contract.

: Previous access level comments are still applicable.
The implementation of status-related methods is correct, but the access level issues noted in previous comments still need to be addressed.
80-82
: Verify the impact of limiting channels to messages feature.
The channel creation has been simplified to only include the messages feature. While this aligns with the current implementation where other features (presence, reactions, typing, occupancy) are not yet implemented, we should ensure this change is intentional.
✅ Verification successful
The channel limitation to messages feature is intentional and correct
The codebase shows that while RoomFeature
enum in RoomFeature.swift
defines multiple features (messages, presence, reactions, occupancy, typing), the current implementation deliberately initializes only the messages channel. This is consistent with a phased implementation approach, where the messages feature is the core functionality, and other features are defined but not yet activated. The error handling and contributor infrastructure already support these additional features for future implementation.

: Consider implementing dependency injection for the lifecycle manager factory
The current implementation hardcodes DefaultRoomLifecycleManagerFactory
, which could make testing more difficult and reduces flexibility. Consider:
- Adding the factory as a parameter to the initializer
- Using protocol-based dependency injection
Here's a suggested implementation:
- public init(realtime: RealtimeClient, clientOptions: ClientOptions?) {
+ public init(
+ realtime: RealtimeClient,
+ clientOptions: ClientOptions?,
+ lifecycleManagerFactory: RoomLifecycleManagerFactory = DefaultRoomLifecycleManagerFactory()
+ ) {
self.realtime = realtime
self.clientOptions = clientOptions ?? .init()
logger = DefaultInternalLogger(logHandler: self.clientOptions.logHandler, logLevel: self.clientOptions.logLevel)
- let roomLifecycleManagerFactory = DefaultRoomLifecycleManagerFactory()
rooms = DefaultRooms(realtime: realtime, clientOptions: self.clientOptions, logger: logger, lifecycleManagerFactory: roomLifecycleManagerFactory)
}
Let's verify the implementation of the lifecycle manager factory:
Sources/AblyChat/Room.swift (3)
Line range hint 22-30
: LGTM! Well-structured status change type
The RoomStatusChange
struct is well-designed with appropriate protocol conformance (Sendable, Equatable) and access levels.
Line range hint 32-51
: Well-designed actor with proper concurrency controls
Good use of the actor model for thread-safe room management. The generic constraint on LifecycleManagerFactory
ensures type safety while allowing flexibility in implementation.
120-127
: Access level issues need to be addressed
The onStatusChange
method and status
property should be marked as public
to match the protocol requirements. This issue was previously identified and still needs to be fixed.
Additionally, verify the lifecycle manager integration:
#!/bin/bash
# Search for lifecycle manager usage patterns
ast-grep --pattern 'func performAttachOperation()'
ast-grep --pattern 'func performDetachOperation()'

: Verify error handling in concurrent scenarios.
While the implementation is thorough, there might be edge cases in concurrent error handling that need verification. The TODO comment on line 49 indicates awareness of this, but we should verify the current implementation's behavior.
Also applies to: 780-780
✅ Verification successful
Let me analyze the concurrent error handling patterns further by checking the implementation details around these channel operations.
Based on the gathered information, I can now provide the final response:
Error handling in concurrent scenarios is properly implemented
The implementation shows a robust approach to concurrent error handling:
- Channel operations (attach/detach) have proper error catching with state verification
- Retry mechanisms are implemented for failed operations with appropriate logging
- Error states are properly tracked through
contributorAnnotations
- The only gap is task cancellation handling, which is already tracked in issue Decide how our SDK should interact with Swift

I'm curious why rooms can't be their own lifecycle managers? Why separated object for just that?
It's a good question; I think that I just did it because I’d been hearing so much about the JS SDK’s “room lifecycle manager” that when I came to implement it in Swift I just created a class of the same name without thinking much about it. We could revisit in the future, but I don't really feel like trying to do that now. |
Replace the existing temporary implementations of room attach / detach / status with those provided by the room lifecycle manager.
Part of #47.
