Describe the steps to reproduce it.

Loading and firing functions like window.nsWebViewBridge.emit causes kill() returned unexpected error 1 in ios

Is there any code involved?

• If possible provide an example project demonstrating the issue.
• Provide a code example to recreate the problem

@ddfreiling Could you have a look at this?

Hi @JungMinHur,

Thank you for reporting this issue.

I don't have access to an iOS device at the moment (I'm on my x-mas vacation), so I can't reproduce it right now.

I noticed your dependency lists tns-core-module@^6.0.0 not 6.2.0, are you sure you're running the 6.2.0-version of NativeScript in the project?

NS 6.3.0 was just released, could you try updating and see, if the problem still exists?

Hi @m-abs ,
Thanks for this great plugin. It worked great until version tns-ios:6.2.0.

After the update to version tns-ios: 6.3.0 my app crashes at startup.
I think the error message: "kill() returned unexpected error 1" is related to a webkit bug.
Also see StackOverflow-Related-Issue.

Nevertheless, the update from tns-ios: 6.2.0 -> 6.3.0 results in the following error:

`CONSOLE WARN file:///node_modules@nativescript\core\application\application.js:312:0: Error: Error: Building UI from XML. @app-root.xml:5:1

Building UI from XML. @views/main/main-page.xml:33:17
Metadata for "NotaWebViewExt." found but symbol not available at runtime.
***** Fatal JavaScript exception - application has been terminated. *****`

I found some related issue here: NativeScript/ios-jsc#1061

It seems to be a problem with the EXTERNAL_SYMBOL_FILE (functions are missing at runtime because the linker by default strips any unused C++ symbols.)

Do you have any idea how this can be fixed?
If you need any further information, please do not hesitate to ask.

My project settings are:
{ "nativescript": { "tns-ios": { "version": "6.3.0" }, "tns-android": { "version": "6.3.1" } }, "dependencies": { "@nota/nativescript-webview-ext": "^6.2.1", "nativescript-directions": "^1.3.1", "nativescript-email": "^1.5.5", "nativescript-iqkeyboardmanager": "^1.5.1", "nativescript-phone": "^1.4.1", "nativescript-secure-storage": "^2.6.0", "nativescript-theme-core": "~1.0.6", "nativescript-ui-listview": "^8.0.1", "tns-core-modules": "^6.3.2" },

Tested on an iPhone6S with iOS: 13.3

@JungMinHur

kill() returned unexpected error 1

We can reproduce this error/warning, but it doesn't seem to break our own app.

@kdagithub

We can't reproduce that error on our systems.

It might be caused by an older version of xcode, do you have the latest version installed?

@m-abs
Currently i am using the cloud build service along with NativeScript-Sidekick.
I prepared a sample project to reproduce the error.
webviewtest.zip

with tns-ios: 6.2.0 no error occurs at startup
with tns-ios: 6.3.0 the app crashes:
crash_tns-ios_6_3_0.txt

Is it possible that the error only occurs when the project is a JavaScript NativeScript-Core Application?

If the error is not reproducible on your side with a local build i would file a bug report for the NativeScript-Sidekick Team (https://github.com/NativeScript/sidekick-feedback)

Thank you very much for your help.

[m-abs]

I think it is caused by the way we bundle the native-classes.
We've never tested it with sidekick builds.

We're working on switching to XCFramework for the iOS classes, in the hope that it solves the problem.

[m-abs]

@kdagithub
Could you try 6.3.0-alpha.0?

We've gone back to pre-building the iOS natives, it will lock on XCode version but should work better.
XCFramework support is broken in nativescript.

@m-abs
I tested Version 6.3.0-alpha.0 on tns-ios: 6.3.0 but the App-crash is still present.
Error: ReferenceError: Metadata for "NotaWebViewExt." found but symbol not available at runtime.

Using Version 6.3.0-alpha.0 with tns-ios: 6.2.0 works.

Do you think that this is related to the WebKit 13.2 (NativeScript/ios-jsc#1220) update in tns-ios: 6.3.0?

[m-abs]

@kdagithub
I doubt it. We don't have the same issue when we build locally.

[m-abs]

@kdagithub could you try the latest alpha? 6.3.0-alpha.1
