[SOLVED] BoringSSL-GRPC unsupported option '-G' for target 'arm64-apple-ios15.0'

BoringSSL-GRPC unsupported option '-G' for target 'arm64-apple-ios15.0'

After updating to Xcode 16 Beta, when building an app, I get this error (in attachments). That's basically it. Is there any way to fix that or should I wait for BoringSSL update?

I've tried pod update and changing Minimum Deployment version. It didn't help.

Solution

If you are using Cocoapods this is a quick fix:

Add this to you Podfile ->

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'BoringSSL-GRPC'
      target.source_build_phase.files.each do |file|
        if file.settings && file.settings['COMPILER_FLAGS']
          flags = file.settings['COMPILER_FLAGS'].split
          flags.reject! { |flag| flag == '-GCC_WARN_INHIBIT_ALL_WARNINGS' }
          file.settings['COMPILER_FLAGS'] = flags.join(' ')
        end
      end
    end
  end
end

After adding the above code > npx pod-install ./ios OR cd ./ios && pod install
