Hello all. We have a KMM project and try to run the App on iOS but when executing the following error comes

Function doesn't have or inherit @Throws annotation and thus exception isn't propagated from Kotlin to Objective-C/Swift as NSError.

and crashes the App. In the class init we call something like this

coroutineScope.launch {
    test()
}

The test function is as followed:

@Throws(Exception::class)
    private suspend fun test() {
       ...
    }

Well, the short answer is you have a crash in your Kotlin code which makes its way to the “Swift/Kotlin” border, at which point it falls over. Whatever calls the

coroutineScope.launch

from Swift is failing. It’s probably wrapping and throwing whatever

test()

throws.

Hello @kpgalligan, thank you i will try the try/catch you suggested.
