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

Looks like a Facebook SDK problem. Please report it there. We can reopen if it's something about Firebase triggering it.

@WillLewis
can you try this solution, see if it works for you or not as I have tried so many ways and this solved my problem?

@KFMONGF2P
I'm not using flutter but a modified version of that worked for me...

• From terminal project directory run pod cache clean --all
• Remove ios/Podfile.lock file
• Go to the Podfile file and ensure it reads platform :ios, '11.0'
• From terminal project directory run pod install
• Run the project again

Thanks
