Runtime IrLinkageError exception when accessing AppScope dependency graph #1627
Description
Description
I have a multi-platform mobile application that targets both iOS and Android. After upgrading Kotlin to 2.3.0, i'm experiencing a runtime crash that only occurs on iOS. Some details to my setup are as follows:
- I have a common AppObjectGraph (expect) and two separate implementations for Android and iOS
- Both actual implementations expose a logger via a variable
- In the iOS actual implementation, i'm also inheriting from LoggingSubgraph
@DependencyGraph(AppScope::class)
actual interface ClientAppObjectGraph :
BaseApplicationObjectGraph,
HasClientViewObjectGraph,
ClientAppManualBindings {
...
val logger: Logger
}
interface ClientAppManualBindings :
LoggingSubgraph,
...
@ContributesTo(AppScope::class)
interface LoggingSubgraph {
@Provides
@SingleIn(AppScope::class)
fun providesLogger(): Logger = KermitLogger(
Kermit(
config = StaticConfig(
minSeverity = KermitSeverity.Debug,
),
),
)
}
The runtime crash occurs on iOS when it creates the AppObjectGraph and tries to access the logger:
class AppState {
static let shared = AppState()
fileprivate let appObjectGraph: ClientAppObjectGraph = createApplicationObjectGraph()
}
extension AppState {
var logger: any Shared.Logger {
appObjectGraph.logger <-- Crash
}
}
The crash is:
Function doesn't have or inherit @throws annotation and thus exception isn't propagated from Kotlin to Objective-C/Swift as NSError.
It is considered unexpected and unhandled instead. Program will be terminated.
Uncaught Kotlin exception: kotlin.internal.IrLinkageError: Abstract property accessor 'logger.' is not implemented in non-abstract class 'Impl'
Self-contained Reproducer
I'll try to provide a small repro separately.
