GRPC Error during builds

Building with Xcode 16 induces errors
unsupported option '-G' for target 'arm64-apple-ios14.0'

This issue was addressed in gRPC 1.65.2 (https://github.com/firebase/firebase-ios-sdk/issues/13115).

But I wasn't able to find if/where it was rolled into Firebase Apple SDK.

I did get a workaround. Adding

    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

to my pod file let the build proceed.

Commencez par vérifier comment ce dépôt sélectionne le Firebase Apple SDK et comment le BoringSSL-GRPC target est compilé pour iOS. Comparez la version de gRPC fournie avec gRPC 1.65.2, puis vérifiez qu’une compilation avec Xcode 16 ne signale plus l’option non prise en charge '-G' sans nécessiter le contournement documenté dans le Podfile.
