some strange errors in K/N target IOS string format. when i format string in this way:

"id:$id,error:$error"

i got error in runtime.both of them are object pass by ios framework callback. the second way is fine：

"id:" + id +",error:" + error

Hi! Can you share a code snippet?

[Luoqiaoyou]

dispatch_async(dispatch_get_main_queue()) {
    wkWebview.evaluateJavaScript(";window.Native2JSBridge && Native2JSBridge._handleMessageFromApp($jsCode);") { id, error ->
        LogUtil.d("WebView", "id:$id,error:$error")
    }
}

[Luoqiaoyou]

inside the LogUtil.kt:

actual fun d(tag: String, msg: String) {
    if (LOG_LEVEL > DEBUG) {
        return
    }
    NSLog("D/$tag : $msg")
}

the error occur on the NSLog call

[Artyom Degtyarev [JB]]

Thanks, can you extend the report with a crash log or something?

[Luoqiaoyou]

its magical. i recompile for give u the crash log. the error just gone🤣

[Artyom Degtyarev [JB]]

That’s fine, I also just build this code successfully. Just save the error code next time, okay? 🙂

[Luoqiaoyou]

again. not only this case. It will appear randomly wherever toString is used

[Artyom Degtyarev [JB]]

Okay, please try to list all details about the situation - what kotlin version are you using here? Is this appearing for simulator or device targets, is it a debug or release framework etc.
IIRC, you can also copy complete stacktrace from Xcode. If it’s possible, post it here too.

[Luoqiaoyou]

simulator, debug, kotlin_version = '1.3.61',
serialization_version = "0.14.0",i dont know how to get the stacktrace from Xcode, i just get this view

[Luoqiaoyou]

look like wild pointer

[Artyom Degtyarev [JB]]

Please try to get complete stack trace somehow like here. Also, it would be helpful to have a project shared - the last screen can possibly be a bug.

Is Kotlin/native toString() equal to Swift description? igot so many problem when i use JsonObject in kotlinx.serialization. idont know is my fault or the compiler or the serialization. Now all I can see is the .h file，i dont know how to debug it

[Luoqiaoyou]

I think the reason for the problem is that the compiler has a problem compiling JsonObject. Declare JsonObject as JsonElement type when used, and it now works https://github.com/Kotlin/kotlinx.serialization/issues/759
