I'm having similar issues trying to instruct qmake to link with it, I have the same app linked on Android (it's even published) but on iOS I also got no luck, this SO also have the same issue:
https://stackoverflow.com/questions/51646982/qt-firebase-c-sdk-linking-issues-on-ios
I have also tried to do what QtFirebase does, and also Qt Cloud Messaging
I'm currently thinking in trying to use cmake but not sure how iOS friendly it is

[crazyhappygame]

The same error is for ios simulator:

I was able to fix it by linking with GSS and Kerberos

if(MACOSX)
    target_link_libraries(${PROJECT_NAME} pthread)
    target_link_libraries(${PROJECT_NAME} "-framework CoreFoundation")
    target_link_libraries(${PROJECT_NAME} "-framework Foundation")
    target_link_libraries(${PROJECT_NAME} "-framework Security")
    target_link_libraries(${PROJECT_NAME} "-framework GSS")
    target_link_libraries(${PROJECT_NAME} "-framework Kerberos")
endif()

Could you update doc ?

Thanks for this input, this seems about right. I will try to get the documentation updated ASAP

When I add Kerberos I get framework not found, where do you get it from?
