[SOLVED] Flutter: Framework not found BoringSSL-GRPC while building for IOS

Flutter: Framework not found BoringSSL-GRPC while building for IOS

I have been working on update for a Flutter app that uses Firebase Firestore, once I finished the updated and starting to build it for IOS, I got the following short error message which cause the build operation to fail:

Error (Xcode): Framework not found BoringSSL-GRPC

So what should I do to get over this problem?

Solution

Since you mentioned that you are using Firebase Firestore in your app, then your case might be the same of mine.

In the official docs of Firebase Firestore for Flutter, you will notice an Optional step that tells you to add a line in the Podfile to improve iOS & macOS build times by including the pre-compiled framework, like this one:

target 'Runner' do
  ...
  # This is the mentioned line
  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '8.15.0'
  ...
end

The solution for me was to ignore this optional step and remove this line from the Podfile. The build operation would take longer than before but it is better than a build failure.
