Compose Compiler 1.5.12+ causes Only @HiddenFromObjC declaration can be a subtype of @HiddenFromObjC declaration

[eygraber]

Describe the bug
Using the compose compiler v1.5.12+ results in the following error when compiling for ios targets:

Only @HiddenFromObjC declaration can be a subtype of @HiddenFromObjC declaration

Affected platforms

• iOS

Versions

• Libraries:
  • Compose Multiplatform version: 1.6.10-rc1 and 1.6.2
• Kotlin version: 1.9.23
• OS version(s) (required for Desktop and iOS issues): macOS 14.4.1
• OS architecture (x86 or arm64): arm64

To Reproduce
Steps to reproduce the behavior:

1. Run ./gradlew assemble on https://github.com/eygraber/vice/tree/renovate/kotlin-monorepo
2. See error

Expected behavior
No error

Additional context
The error is reported on this line:

public abstract class FlowSource<T> : ViceSource<T>

where ViceSource is:

public interface ViceSource<T> {
  @Composable
  public fun currentState(): T
}

Originally reported here because I thought it was an issue with Kotlin 1.9.24, but then I tested on Kotlin 1.9.23 with all compiler versions starting from 1.5.12 and was able to repro the issue.

the problem was in name clash (ViceSource class inherited hide annotation due to ViceSource composable function)
should be fixed in 1.5.13.2 for kotlin 1.9.23 & 1.5.13.3 for kotlin 1.9.24

Hi, @Kashif-E , make sure you updated compose compiler to version 1.5.13.2 (for kotlin 1.9.23) / 1.5.13.3 (kotlin 1.9.24) or updated Compose Multiplatform to version 1.6.10-rc02
