Have you tried this yet? https://stackoverflow.com/questions/52536380/why-do-i-get-ios-linker-errors-with-my-static-libraries and https://github.com/wuxudong/react-native-charts-wrapper/issues/604#issuecomment-548541820

@baronha I already added the Swift file and headers.

the second link which u shared says add pod 'RNCharts', :path => '../node_modules/react-native-charts-wrapper', do we have anything like this for CropViewController?

Absolutely OK. You should try that!

[sarafhbk]

@baronha what should i try? adding what in place of RNCharts?

[baronha]

Wait. I think this error is mainly in your Flipper configuration. Show me your Podfile

@sarafhbk I think if you use this library it is not necessary to use additional pod 'react-native-image-crop-tools', :path => '../node_modules/react-native-image-crop-tools'

[sarafhbk]

@baronha after removing the pod 'react-native-image-crop-tools', :path => '../node_modules/react-native-image-crop-tools' also the error still remains. i use this package because i need a standalone image cropper for edit image feature.

standalone image cropper will be deployed in the future in react-native-multiple-image-picker@latest. Back to the above error. You have deleted Podfile.lock & /Pod and re-installed pod-install

[sarafhbk]

@baronha yes i did delete the pods, pod.lock and pod install still the same issue. I think the issue might be both packages use TOActivityCroppedImageProvider in common.

[sarafhbk]

@baronha do u suggest anything? im stuck with this issue for a very long time. everytime i had to change the version for ios and then make builds

[fukemy]

this error say that you have duplicate class named like TOActivityCroppedImageProvider, let search and find another lib use this class.

1. If you does not tend to use this lib that have same class too, just remove it, then problem will gone
2. If you must do this, so you need to fork one lib as local library then modify the filename
