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

Now, even going back to firebase 12.1, I still have the same errors.

This would indicate that the C++ libraries are missing. For iOS, they should be in Assets/Plugins/iOS/Firebase/libFirebaseAppCpp.a Can you verify that file is there, and is enabled for iOS. If it is, check the XCode project, to make sure it was included correctly. It would likely be in Unity-iPhone/Libraries/Plugins/iOS/Firebase

mls-icaro commented 2 weeks ago

checkings: Assets/Plugins/iOS/Firebase/ in this folder there are :

libFirebaseCppApp.a
libFirebaseCppMessaging.a

They are enable for iOS

I also check in the XCode project the Unity-iPhone/Libraries/Plugins/iOS/Firebase. The files are in this folder.

Solution: I set the old version again of the firebase sdk 12.1.

delete files in /Users/youruserhere/Library/Developer/Xcode/DerivedData/
XCode (Product->Clean Build)
gem uninstall cocoapods
sudo gem install cocoapods
do the Unity IOS build to generate XCode project
check podfile and versions and if there is a xcworkspace file generated.
in xcode project via terminal:
- pod cache clean --all
- pod deintegrate
- pod repo update
- pod install (check if there are errors and fix them)

PS: I put also in Other Linker Flags of Unity Framework target: -ld_classic. In Unity-IPhone target I put in Build Phases tab -> Add a New Run Script Phase

cd "${CONFIGURATION_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}/Frameworks/UnityFramework.framework/"

if [[ -d "Frameworks" ]]; then

 rm -fr Frameworks

fi
