🐛 Vision Camera crashes when built with Xcode 14 #1244

jpudysz · 2022-09-15T09:08:10Z

What were you trying to do?

I was trying to build my app with Xcode 14.

Reproduceable Code

No super fancy code. Simply render the camera with a frame processor. I'm using QR code scanner:


const [frameProcessor, barcodes] = useScanBarcodes([BarcodeFormat.CODE_128])

return (
    <Camera
       device={device}
       isActive={isActive}
       frameProcessorFps={5}
       frameProcessor={frameProcessor}
       style={StyleSheet.absoluteFillObject}
    />
)

What happened instead?

The app crashed with an error from HostFunction.

I can confirm that code works as expected when built with Xcode 13.

Hello @jpudysz, could you add your react-native/react-native-vision-camera versions please ? :)

jpudysz · 2022-09-15T09:33:00Z

Sure!

"react-native": "0.69.5",
"react-native-vision-camera": "2.14.1",
"vision-camera-code-scanner": "0.2.0"

icc-guerrero · 2022-09-15T10:21:54Z

Similar issue here.

[javascript] Frame Processor threw an error: Can't find variable: __xxxx

baylesa-dev · 2022-09-15T11:24:59Z

I'm able to reproduce the issue (repro https://github.com/baylesa-dev/rn_vision_camera_xcode_14)

Edit: Just tried with https://github.com/mrousavy/vision-camera-image-labeler, and it works perfectly: the issue seems to be related to the swift implementation of https://github.com/rodgomesc/vision-camera-code-scanner

jpudysz · 2022-09-15T13:03:11Z

Nice catch @baylesa-dev!
The problem is that we can't even call this plugin. It breaks before callback:
https://github.com/rodgomesc/vision-camera-code-scanner/blob/0571128d46a4a7564aca97d9271c8f7c0b67a5d7/ios/VisionCameraCodeScanner.swift#L11

baylesa-dev · 2022-09-15T13:05:45Z

Yep!

console.log(typeof __labelImage) // => function
console.log(typeof __scanCodes) // => undefined

jpudysz · 2022-09-15T15:06:22Z

I also checked vision-camera-face-detector, and it crashed immediately. The only difference between all these plugins is that vision-camera-image-labeler has been written with Objective-C instead of Swift.

I suspect that VISION_EXPORT_SWIFT_FRAME_PROCESSOR is not registering frame processors correctly or something else breaks this registration in Xcode 14.

Same issue

baylesa-dev · 2022-09-15T18:54:04Z

Mentioned in facebook/react-native#34673 (comment)

ArturoTorresMartinez · 2022-09-15T23:58:24Z

Same here, any more info we can provide to help patch this?

Or is there a temp workaround?

jpudysz · 2022-09-16T07:36:28Z

So far, nothing I'm aware of.
I was trying to patch Podfile with the solutions mentioned in the linked issue, and the app is compiling indeed, but vision camera plugins are not working.

We need to wait for a patch from react-native.
To run your app smoothly, you need to downgrade Xcode to version 13.4.

Thanks @jpudysz , I can confirm downgrading to version 13.4 solves the issue for now.

I'll also keep this thread updated if I hear any updates or workarounds.

Thanks! 👍

bglgwyng · 2022-09-18T09:57:24Z

I have this issue after upgrading RN to 0.70.1
My XCode version is 13.4.1.

I made a repo to reproduce the issue.
https://github.com/bglgwyng/FrameProcessorExample2

In my case, scanCodes from vision-camera-code-scanner works fine.
However, my custom empty frame processor xyz that is scaffolled with vision-camera-plugin-builder crashes the app with the same error message here.

Thanks, I confirm that this solution works, for me is just a temporary workaround, because I need to deploy to the latest iOS, so I had to downgrade to Xcode 13.4 and then add support for iOS 16.0

Hope this will be fixed also for the latest Xcode version

In this thread you can find, how to add support

VISION_EXPORT_SWIFT_FRAME_PROCESSOR is working on my main Project, but not working in pod project like vision-camera-code-scanner when build by Xcode 14.0.

If I chagne this code __attribute__((constructor)) static void VISION_CONCAT(initialize_, objc_name)() to +(void)load

then it work (temporary). I tested it.

Thanks @intmain , it fixed the issue for me temporarily too. It seems that using attribute((constructor)) no longer works with load() and not sure why swift bridge to objc works (using +(void)load )

(I'm not familiar with swift, so if I was wrong with something, please correct me.)

The method posted by @intmain only solves crashes caused by upgrading to Xcode 14 - which means if you're having problems with Xcode 13.x, then the problems are probably elsewhere.

Hmm, I took a look at your frame processor and it seems you didn't add any code besides the example in doc. If that is the case then I suggest you open a separate issue and ask for help there.
