I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @OscarFyl, I tried to reproduce the issue, but I'm able to successfully run the app. Could you provide your Podfile and Podfile.lock file?

Same error as in #12605. Need more details to know if it's the same root cause.

Podfile.txt
Podfile.lock.txt




Hello
The file contains my podflile file and podflile.lock file, as well as screenshots of my project error reports. I was using version 10.20.0 before. When I upgraded to version 10.23.0, I would get the error 'FirebaseCrashlytics/FirebaseCrashlytics-Swift.h' file not found'. I tried the following:
1.clean project
2. Re-execute pod install and pod update
3. Cleaned up the DerivedData directory of xcode,
4. Exit Xcode and restart
None of the above four methods will work.
I can't find this file when I search for FirebaseCrashlytics-Swift in my project. I can't find it in the folder through show in finder. Where does this file exist?
My computer system is: Sonoma 14.4
Xcode version is: 15.3

Hey @OscarFyl
This is the same error as #12605 mentioned, you need to uncomment use_frameworks! line. As @paulb777 mentioned in that issue use_frameworks! is required since Firebase 9.0. More details in the release notes - https://firebase.google.com/support/release-notes/ios.

Hello, I have the same problem.

But since the version 10.22.1 everything worked well.
I've never included use_frameworks! but I included use_modular_headers! instead and until the version 10.22.1 it was working,

Did something change ?

I experienced similar building errors after updating Firebase SDK in the past with static linking, as others recommends you have to switch to use_frameworks!, which means Firebase will be linked dynamically. However it can lead to duplicated symbols. Moreover the mix of static and dynamic linking could cause transitive dependencies as well.

The following solution is working for me well, with keeping all my other dependencies as static libraries (starting the podfile specification still with use_modular_headers!).

pre_install do |installer|
  installer.pod_targets.each do |pod|
    if pod.name.start_with?("Firebase")
      def pod.build_type;
        Pod::BuildType.dynamic_framework
      end

      pod.recursive_dependent_targets.each do |dep_pod|
        def dep_pod.build_type;
          Pod::BuildType.dynamic_framework
        end
      end
    end
  end
end

Hey @paul-lavoine

We added a swift module in Crashlytics for 10.23.0 #12410. This is related to change in release note for 10.23.0 https://firebase.google.com/support/release-notes/ios#crashlytics

My project also got hit with this issue. 30+ external libraries, 10+ spm packages, mix of ObjectiveC + Swift codebase.

After applying the suggested fixes above, Xcode choke on more errors... 🤮

reverting back to 10.22.0 until a stable build-compatible release.

My project also encountered this problem. I saw that this has been closed, but how to solve it?

Podfiles should include either use_frameworks! or use_frameworks! :linkage => :static

Podfiles should include either use_frameworks! or use_frameworks! :linkage => :static

Hi @paulb777, use_frameworks! doesn't work for my project as there are a lot of old dependencies, the project contains OC and swift modules, I tried use_frameworks! :linkage => :static, but encounter this error after pod install. I checked the SWIFT_VERSION config, all swift modules set it to 5.0. I searched and tried different solutions but still failed. Can you give me some advices? Thanks.

Hi @haozhutw, checkout these suggestions (option 1, option 2). They may help address the errors you've shared.

Hey @paulb777 , after adding use_frameworks! in the Podfile caused many errors related to "Module map 'xxxx' not found" when building the unit tests. What can be the workaround here? Thks!

Hi @haozhutw, checkout these suggestions (option 1, option 2). They may help address the errors you've shared.

Thanks, option 1 doesn't work, with option 2 I can pod install successfully, but other errors occurred when I build the project. I have to revert the update, Firebase 10.23 totally breaks my project, 10.21 and below works well.

Reopening to investigate making a less-disruptive migration to the Swift-implementations.

What version has this fix?

@tomerh2001, this fix has been checked in and will be released in Firebase 10.24 (due out week of April 9).

Oh I see. This bug is currently preventing us from compiling our app, any temp workarounds for now? We're using:

    "@react-native-firebase/analytics": "^19.1.1",
    "@react-native-firebase/app": "^19.1.1",
    "@react-native-firebase/app-distribution": "^19.1.1",
    "@react-native-firebase/crashlytics": "^19.1.1",
    "@react-native-firebase/perf": "^19.1.1",

If I understand correctly you are the not the maintainers of these, but they do use this package under the hood - so maybe a version that previously worked (and I'll find the matching react-native-firebase/crashlytics version)

@tomerh2001

Downgrading @react-native-firebase to ^18.3.0 fixed for me.
