There is a description in Objective-C interop: Note that the opposite reversed translation is not implemented yet: Swift/Objective-C error-throwing methods aren't imported to Kotlin as exception-throwing. So, I want to know how can I catch the error from the Objective-C function? For example. How can I catch

NSDecimalNumberDivideByZeroException

when I invoke

NSDecimalNumber.decimalNumberByDividingBy

function? I've used

runCatching

to wrap the invocation, but it doesn't work.

You cant catch them unfortunately. From the docs:

OK, but this still is a flaw of kotlin multiplatform. We cannot check the errors in advance because some errors occurred in the platform-specific functions. Anyway, thanks to your response.
