Swift pods cannot yet be integrated as static libraries FirebaseCoreInternal-library

Question

I am building an app by Flutter. I got this error message when doing "pod install" or "pod install --repo-update" or "pod update" and the pod install failed and stopped.

The error message:

[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod FirebaseCoreInternal-library depends upon GoogleUtilities-library, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set use_modular_headers! globally in your Podfile, or specify :modular_headers => true for particular dependencies.

My Podfile:

platform :ios, '11.0'

...

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

...

Solution 1

I rewrote my code like this:

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  pod 'Firebase/Analytics'

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

Then I am doing cd ios and pod install and it works for me.

You can find more information here: https://firebase.google.com/docs/ios/setup#available-pods

You can also find a sample and open a project repository here: https://firebase.google.com/docs/samples.
There you can view the config/Podfile file and use it as an example.

Solution 2

You may not need to use use_frameworks! or use_modular_headers! because it's getting conflict with use_flipper

You can add the following without using them:

  pod 'Firebase', :modular_headers => true
  pod 'FirebaseCoreInternal', :modular_headers => true
  pod 'GoogleUtilities', :modular_headers => true
  #....add any library need headers

Same issue when I upgrade my Xcode and Firebase version. Got any idea to solve this issue? I am trying to use another method to import firebase (xcode package manager), not sure if it works or not.
