It is safe to use KClass<T>.serializer() even if is internal?

I’m working on a Multiplatform project and I’m building a custom serializer for Alamofire to deserialize a json to a Kotlin Class. That’s because I have all the DTOs on KMP side.

The way I found to achieve this is by using the KClass<T>.serializer() method that is marked as InternalSerializationApi. So I was wondering if it is safe to use or there is another way that I don’t know.

object JsonDecoder {
    @InternalSerializationApi
    fun decodeFromString(jsonString: String, objCClass: ObjCClass): Any {
        val kClazz = getOriginalKotlinClass(objCClass)!!
        val serializer = kClazz.serializer()
        return Json.decodeFromString(serializer, jsonString)
    }
}

Swift Code:

struct Serializer<T>: ResponseSerializer {
    func serialize(request: URLRequest?, response: HTTPURLResponse?, data: Data?, error: Error?) throws -> T {
        do {
            let x = try JsonDecoder().decodeFromString(jsonString: "{ }", objCClass: T.self as! AnyClass) as! T
            return x
        } catch {
            throw AFError.responseSerializationFailed(reason: .decodingFailed(error: error))
        }
    }
}

Thanks

Hi @mltbnz and @Baileypollard, I’ve updated the project with the new memory model and new dependencies and everything is working for me!

@prof18 I am running into Terminating app due to uncaught exception 'NSGenericException', reason: 'Class BaseResponseDTO is abstract and can't be instantiated' on the Swift side when using your solution.
