Expo: iOS Build

[spsaucier]

I had this working on a bare RN app, but I'm trying to migrate it to Expo now, and it's no longer building on iOS.

It gives this error:

› Copying   VehoDrivers Google-Maps-iOS-Utils/GoogleMapsUtils.framework/Headers/GMSMarker+GMUClusteritem.h ➜ ios/Pods/Google-Maps-iOS-Utils/Sources/GoogleMapsUtilsObjC/include/GMSMarker+GMUClusteritem.h

RN Vision Camera version:
"react-native-vision-camera": "^4.6.3",

I'm using expo-devlauncher and this setup in app.config.ts:

      [
        'react-native-vision-camera',
        {
          enableCodeScanner: true,
          cameraPermissionText:
            'We need access to your camera for scanning barcodes and taking pictures of your drop-offs.',
        },
      ],

I've also tried adding these to expo-build-properties (also tried without):

      [
        'expo-build-properties',
        {
          ios: {
            useFrameworks: 'static',
            buildSettings: {
              VisionCamera: {
                buildType: 'static_library',
              },
              'vision-camera-code-scanner': {
                buildType: 'static_library',
              },
            },
          },
        },
      ],

I'm using the branch which has TextRecognition set to 6.0.0, but I don't think that is related to this error (it was necessary for getting this far in the build).

Any ideas about how I can resolve this?

I was having a similar issue. In my case, it was related to the use_frameworks! Podfile requirement for Firebase. The fix is here: rodgomesc/vision-camera-code-scanner#62

In the Podfile, I added the fix below after the use_frameworks lines, which worked.

  use_frameworks! :linkage => :static
  use_frameworks! :linkage => podfile_properties['ios.useFrameworks'].to_sym if podfile_properties['ios.useFrameworks']
  use_frameworks! :linkage => ENV['USE_FRAMEWORKS'].to_sym if ENV['USE_FRAMEWORKS']

  # vision camera fix
  # some indication the use_frameworks keyword is causing issues
  # see: https://github.com/rodgomesc/vision-camera-code-scanner/issues/62
  pre_install do |installer|
    installer.pod_targets.each do |pod|
      if pod.name.eql?('VisionCameraOcr') || 
         pod.name.eql?('VisionCamera')
        def pod.build_type
          Pod::BuildType.static_library
        end
      end
    end
  end
