Compilation error on generated code when using @ObjCName(swiftName = "_")

[aoriani]

I used @ObjCName(swiftName = "_") with the goal of not requiring Swift callers to pass the parameter name. But that seems to create a problem for the code generator. It sets an empty string for the Objective-C name for the parameter

Input Code

suspend fun fetchString(@ObjCName(swiftName = "_") param: Int): String {
    println("Starting")
    delay(100)
    withContext(Dispatchers.IO) {
        println("in some IO thread")
        delay(1000)
    }
    println("back on original thread")
    return param.toString()
}

Generated Code

@OptIn(ExperimentalObjCName::class)
@ObjCName(name = "fetchString")
public fun fetchStringNative(@ObjCName(name = "", swiftName = "_") `param`: Int):
    NativeSuspend<String> = nativeSuspend(null) { fetchString(`param`) }

Compiler error

Empty @ObjCName names aren't supported

Thanks for the report! This has been fixed in v1.0.0-ALPHA-14.
