Temp. fix would be to set the "Deprecated Functions" setting in Pods to 'No' this will ignore the error but it's still exists.

@KevinVladG Thanks for the report. What's the reason for changing the pods build optoins to Swift 5 and how exactly are you doing that? Most of the Firebase pods are written in Objective C and support back to iOS 8 or 9.

We can potentially ifdef the code to address this, but I'm curious to get more context about the use case.

@paulb777 I updated the Firebase pods using Xcode 12 Issues navigator. There was an option for my current project and for the pods and such. that would be great! I just wanted to be sure you guys were aware of it on this new release.

@KevinVladG Sorry, the fix was a bit more complicated than I initially thought and we haven't been able to prioritize yet

@paulb777 no worries I have been following along. I've silenced the warning so no worries!
