react-native-vision-camera: [V2] iOS - App Crashes at Launch when built with Xcode 15

I’m on version 2.15.4 and had to replace

+(void)load

with

__attribute__((constructor)) static void VISION_CONCAT(initialize_, objc_name)()

in two lines in the file ./ios/Frame Processor/FrameProcessorPlugin.h:

This avoids the initial crash. Haven’t tried the camera which I assume will crash as stated in https://github.com/mrousavy/react-native-vision-camera/issues/1307#issuecomment-1727739161.

This patch worked for me!

react-native: 0.71.13 react-native-camera-vision: 2.15.4 xcode: 15 macos: 14.0

Same issue after updating to xcode 15

So basically the breaking change from Xcode 13 -> 14 is now reverted with Xcode 14 -> 15? 😂

I’m on version 2.15.4 and had to replace

+(void)load

with

__attribute__((constructor)) static void VISION_CONCAT(initialize_, objc_name)()

This avoids the initial crash. Haven’t tried the camera which I assume will crash as stated in #1307 (comment).

Thank you, that’s worked for me!

Note: I am using RN 0.68.2 here.

@Thormeard, it’s final change, worked for me. But only to “react-native-vision-camera”: “2.15.2”, if I update “react-native-vision-camera” to 2.16.1 I got error(Frame processors not enabled) again, I don’t know why .

Same issue here. It works with Xcode 14, but can’t build for iOS 17.

Facing the same issue. App crashes on launch.

Yep, same issue. Xcode 15 (15A240d).

Facing the same issue! Any workarounds for this on xcode 15?

@Thormeard, it’s final change, worked for me. But only to “react-native-vision-camera”: “2.15.2”, if I update “react-native-vision-camera” to 2.16.1 I got error(Frame processors not enabled) again, I don’t know why .

Hi, got the same issue. (2.16.1) Managed to fix crashing on startup with https://github.com/mrousavy/react-native-vision-camera/issues/1307#issuecomment-1731248952 But still got an error when trying to use frame processor: frame-processor/unavailable: Frame Processors are not enabled.

Anything else im missing?

@gabrielmaldi @DanielAraldi be warned (I mentioned this in my original comment), the reversion fixes the startup crash but the original crash (using the camera with a frame processor) will pop back up, making the fix unusable

The quick fix for now is to revert this change - https://github.com/mrousavy/react-native-vision-camera/pull/1308/files

Replacing vision-camera-code-scanner with react-native-camera-kit.

That solved the issue for me.

@ms314006 Just keep using Xcode 14 for now. I recommend using https://github.com/XcodesOrg/xcodes to manage Xcode versions. But we need to get this resolved eventually, because at some point next year Apple will likely require Xcode 15 for submissions.

@phatmovista Yes, but unfortunately reverting it is not an option because the app crashes when using the camera (the original reason the change was put in: https://github.com/mrousavy/react-native-vision-camera/pull/1308)

Same issue after updating to xcode 15

Same issue here 😭, This message is printed to the xcode15 console before crashed:

@marcshilling Do you have any solution for the issue? I will be grateful for anything you can reply. 🙏

gettins this issue also on xcode 15 + iOS 17+ vision camera 3.3.1.

Hey - yea please submit a PR instead of creating random patches. Then I can merge and backport it.

@Thormeard, it’s final change, worked for me. But only to “react-native-vision-camera”: “2.15.2”, if I update “react-native-vision-camera” to 2.16.1 I got error(Frame processors not enabled) again, I don’t know why .

Also If you have firebase with use_frameworks! :linkage => :static in your pods this can help you (this case give same error: Frame processors not enabled ):

    installer.pod_targets.each do |pod|
      if pod.name.eql?('VisionCamera') || pod.name.eql?('RNReanimated')

#1840 (comment)

Can confirm, fixes issue for me BUT only on 2.15.2 (not on latest 2.16.1). Thanks!

Xcode 15, ios 17, iPhone X

This should solve the issue permanently - https://github.com/mrousavy/react-native-vision-camera/issues/1307#issuecomment-1731248952

crash is resolved with this. thx

__attribute__((constructor)) static void VISION_CONCAT(initialize_, objc_name)()

however I can’t use camera.

"react-native-vision-camera": "2.16.1",
"react-native": "0.68.7",

__attribute__((constructor)) static void VISION_CONCAT(initialize_, objc_name)() \
{                                                                                   \
  [FrameProcessorPluginRegistry addFrameProcessorPlugin:@"__" @ #name callback:^id(Frame* frame, NSArray<id>* args) {    \
    return [objc_name callback:frame withArgs:args];                               \
  }];                                                                               \
}

Yes, this is a temporary fix to be able to at least work on the rest of the app. Thanks a lot.
