I'm trying to use the updateApplicationContext() function from WatchConnectivity on iOS. The function throws which seems to translate to a parameter error of type kotlinx.cinterop.CPointer<kotlinx.cinterop.ObjCObjectVar<platform.Foundation.NSError?>>?, does somebody know how I can get this error if the function throws?

Maybe something like this?

memScoped {
    val error = alloc<CFErrorRefVar>()
    val key = SecKeyCreateRandomKey(attributes, error.ptr)
    (CFBridgingRelease(error.value) as? NSError)?.let {
        println("ERROR: ${it.debugDescription}")
    }
}
