[Venkat , Bangalore , India]

Hi Everyone.. Could you please help me with below issue.. it works fine in Android, but crashed in iOS......

IDEA Version:
IntelliJ IDEA 2020.2.2 (Community Edition)
Build #IC-202.7319.50, built on September 15, 2020
sample code:
interface IElement{}

@Serializable
@SerialName("Item")
data class ElementImpl:IElement

class JsonExporter {
suspend fun export(): String {
val module = SerializersModule {
polymorphic(IElement::class, ElementImpl::class, ElementImpl.serializer())
}

val elementsList<ElementImpl> = ...
val jsonString = Json { serializersModule = module }.encodeToString(elementsList)
return jsonString
}
}

Multiplatform setup:
dependencies {
//others
classpath "org.jetbrains.kotlinkotlin serialization1.4.10"
}

plugins {
id 'org.jetbrains.kotlin.multiplatform' version '1.4.10'
id 'org.jetbrains.kotlin.plugin.serialization' version '1.4.10'
}

sourceSets {
commonMain {
dependencies {
//serialization
implementation "org.jetbrains.kotlinxkotlinx serialization json1.0.0-RC2"
}
}
}

Error:
Exception doesn't match @Throws-specified class list and thus 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: kotlinx.serialization.SerializationException: Serializer for class 'IElement' is not found.
Mark the class as @Serializable or provide the serializer explicitly.
On Kotlin/Native explicitly declared serializer should be used for interfaces and enums without @Serializable annotation


External Libraries that got added transitively after i added "kotlinx-serialization-json:1.0.0-RC2"
Gradle: org.jetbrains.kotlinxkotlinx serialization core iosx64klib:1.0.0-RC2

Downgraded to 1.3.72 kotlin plugin and serialization to 0.20.0... works fine in both android /ios... seems with new plugin there is a problem
