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:

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 in the case of divide by zero, just check your divisor isnt zero before calling and throw your own exception

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.
