duplicate symbols for architecture x86_64

@jp928 I have same error, please say how did you fix it?

[jp928]

@vladimixz I forgot to remove the deprecated rn-fetch-bolb. This will cause duplicated symbol.

But I am using rn-fetch-bolb in my app and it is working fine. I don't want to remove it because that functionality is working fine. What should I do ?

[jp928]

@Anujmoglix This library is an alternative of rn-fetch-bolb. you have to choose one to go forward not both.

what library??

[Anujmoglix]

@aallvi use either react-native-blob-util or rn-fetch-blob . You can't use both in package.json Try to remove rn-fetch-blob because it is not maintained now.

Before deleting rn-fetch-blob, you need to search for other package dependencies, otherwise it will be deleted from package.json file but not from node_modules folder.

1. Press npm list --depth=2 at project root folder and search for packages with dependency on rn-fetch-blob
2. In my case was redux-persist-filesystem-storage
3. Update redux-persist-filesystem-storage to latest version which depends on react-native-blob-util
4. npm uninstall rn-fetch-blob
