[iOS] duplicate symbols for architecture (libSSZipArchive.a and libJWT.a)

[mistikk]

When I try to get build for iOS project, it is getting error about duplicate symbols. It is about libSSZipArchive.a and libJWT.a libraries.

I investigated all issues about that. Before v5.2.2, we could ignore jwt and SSZipArchive libraries with subspecs. But this feature removed with this pr #1210. I think we can find a solution for that or add again to subspecs.

Same issues before v5.2.2;
#1378
#1123
#1114
#241

Steps to Reproduce

1. react-native link react-native-code-push
2. react-native run-ios

Expected Behavior

Successful build

Actual Behavior

What actually happens?

Hey @mistikk,
Thanks for reporting!

I've cloned your project and used this:

• react-native link react-native-code-push
  
• react-native run-ios

App launched without this error. What should I do to reproduce the issue?

[mistikk]

@yuri-kulikov did you link all of libraries, because it throws duplicate library error on me, so if you linked just code-push, it launches as successfully

[yuri-kulikov]

@mistikk, Oh, you're right, I guess I missed that moment. I'll link all the libs and test it again, thanks!

[yuri-kulikov]

Hey @mistikk, Sorry for the delay, I have some problems reproducing the issue.
As far as I can see, the libraries are already linked in your app and you use updated react-native-code-push plugin. Could you help me with a simple step-by-step instruction on how to reproduce the issue using your application?

[mistikk]

Yes right I updated to code push library for fix to this issue.

1 - Change react-native-code-push version with lastest on package json (v5.6.0)
2 - run react-native link code
3 - run react-native run-ios code

After that you should see this error. If you cannot see, please remove cache and get clean build

[yuri-kulikov]

@mistikk, thanks!

I've tried to do it but faced this:

Could you try to test these steps on a fresh git clone folder?

I'm also seeing this same error now that I've begun migrating from the Legacy Build System to the Modern Build System. happy to provide any information that might help get to the bottom of this.

[yuri-kulikov]

Hey @jkepps, I would be very grateful if you could help me with some simple demo app to reproduce the issue or at least some steps to reproduce it!

Is there any update on this? I am getting the same issues with duplicate symbols 🤦‍♂

[rodrigomf24]

For those who are still stumbling with this issue and are using a RN version < 0.59 try these steps:

yarn add react-native-code-push@5.2.2 
react-native link react-native-code-push
cd ios && pod install

then open xcode worskpace and rebuild

This worked for me
