Is there a built in way to convert a `Throwable` into a `NSError` or `NSException`?

Is there a built in way to convert a Throwable into a NSError or NSException?

Yes. https://kotlinlang.org/docs/reference/native/objc_interop.html#errors-and-exceptions

[ribesg]

I don’t see anything related to what I asked

So if Swift or Objective-C code calls a Kotlin method which throws an exception to be handled, then the Kotlin method should be marked with a @Throws annotation. In this case all Kotlin exceptions (except for instances of Error, RuntimeException and subclasses) are translated into a Swift error/NSError.

The interoperability should handle that for you.

[ribesg]

Not really, I just have a function that has a Throwable parameter and calls a function taking a NSError. I’m not talking about automatic thrown error translation

Still an open question.

I also like to hear the answer

Hello folks, do we have an update on it? Can we manually convert Throwable into NSError? Or if there is an alternate? I need to check if it is a network/connectivity error from kotlin
