After running pod install it removing the react and also after unlinking the packages podfile not showing any third party packages in latest react-native version(0.60.0)

[nihp]

I am upgrading the react-native versions.

I have run pod install before unlinking the packages and then perform unlink and then I have run pod install.

After this, it shows react missing. So again I added all the removed packages in podfile and run pod install.

Now I am facing the react-missing and React/RCTBundleURLProvider.h' file not found error.

I have tried with clean pod, node_modules and derived datas but nothing worked for me.

Any solution?

Can you run react-native info and edit your issue to include these results under the React Native version: section?

If you believe this information is irrelevant to the reported issue, you may write `[skip envinfo]` alongside an explanation in your Environment: section.

Please make sure that you follow https://react-native-community.github.io/upgrade-helper/ thoroughly, and please note that 0.60 features auto-linking feature.

Thanks I already saw this.

I have a question @dulmandakh My Podfile target has a lot of third party packages before after run pod install and I have unlinked all packages and the Podfile not showing the third party packages. Did you know the reason?

Now it is empty. If I add pod and paths which I had before it shows the error as need to unlink

If I remove and run the app it not shows this error.

Also I am facing React/{.h} not found error for more than 2 weeks. I can'table to fix that. I tried many solution nothing get fixed
