Hi, I have Serializable class and I used kotlinx.serialization, did someone know how I can use it in iOS SWIFT?
I’m trying to parse JSON with the class I’d created

Hi,

Hi, I have Serializable class and I used kotlinx.serialization, did someone know how I can use it in iOS SWIFT?

What is “it”?
Are you trying to parse JSON to Kotlin class from Swift?

I build multi platform library in Kotlin and now I’m trying to use it on iOS

You can define Kotlin function that serializes or deserializes particular Kotlin class, and then use this function from Swift.

I did that and then I got this error: “Instances of kotlin.Error, kotlin.RuntimeException and subclasses aren’t propagated from Kotlin to Objective-C/Swift.
Other exceptions can be propagated as NSError if method has or inherits @Throws annotation.
Uncaught Kotlin exception: kotlin.NotImplementedError: An operation is not implemented: Obtaining serializer from KClass is not available on native due to the lack of reflection. Use .serializer() directly on serializable class.”

This error contains all the required information to fix it.

Use .serializer() directly on serializable class

I’ll try again

can you send me an example please?
