I'm trying to integrate firebase for cloud messaging(FirebaseMessaging) in my objective c project, when I do pod install facing below issue. My project is also having custom libraries.

Below are my .podspec and pod files.

to resolve above issue, I have added "use_modular_headers!" in my pod file and did pod install successfully.

when I open the app and trying to compile but I'm surprised that I have facing issues from my existing custom libraries which are successfully build before firebase integration in the app.

Please check the below file for the reference.

can anyone help on this issue?

Thanks in advance.

Add use_frameworks! or use_frameworks! :linkage => :static to the Podfile.

Firebase 9 dropped support for CocoaPods library integrations. More details in the release notes.
