Hey @alistair-riskmemo - try dropping Cocoapods. See this comment: #13563 (comment)

Next, you will want to ensure you're pulling latest level-db Pod. Try the following:

cd ios
rm -rf Pods && rm Podfile.lock
pod install --repo-update

You're aiming for level-db 1.22.6 which is a transitive dependency that you can see in your ios/Podfile.lock.

Let me know if this resolves your issue 👍

[alistair-riskmemo]

Hi @russellwheatley, thanks for your help.

After doing that it's started throwing different errors. I tried removing the test project and starting again from scratch as well. I'm getting this a lot now:
Error (Xcode): Undefined symbol: absl::lts_20240116::ByString::Find(absl::lts_20240116::string_view, unsigned long) const

Either way, I think the original error will still remain. 1.22.6 is elsewhere in the Podfile.lock, but it's FirebaseFirestoreInternal depending on 1.22 which is causing the original error:

• FirebaseFirestore (11.2.0):
  • FirebaseCore (~> 11.0)
  • FirebaseCoreExtension (~> 11.0)
  • FirebaseFirestoreInternal (= 11.2.0)
  • FirebaseSharedSwift (~> 11.0)
• FirebaseFirestoreInternal (11.2.0):
  • abseil/algorithm (~> 1.20240116.1)
  • abseil/base (~> 1.20240116.1)

It's issue #13563 I'm getting now. I just updated to the latest cocoapods 1.16.1

[russellwheatley]

@alistair-riskmemo drop cocoapods down to v1.15.2

[mikehardy]

@russellwheatley with an update to leveldb-library and this below, things are fine on full-current stuff. Exciting times when the build toolchains update!

---

[note: this was edited to be gnu++14 not c++14]

Add this to your Podfile if you want a workaround, note you may already have a post_install section, so you would just use the inner part(s):

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'abseil'
      Pod::UI.puts "Workaround: Configuring abseil to use gnu++14 language standard for cocoapods 1.16+ compatibility".yellow
      Pod::UI.puts "            Remove workaround when upstream issue fixed https://github.com/firebase/firebase-ios-sdk/issues/13996".yellow
      target.build_configurations.each do |config|
        config.build_settings['CLANG_CXX_LANGUAGE_STANDARD'] = 'gnu++14'
      end
    end

You will need to run pod install again after adding this, so that it executes and updates the build setting
