How to solve “duplicate symbol” when added Firebase in Xcode

Question

I can\'t solve the error \"duplicate symbol\".

The error is

Answer 1

I solved the issue by

1. Deleting everything from my podfile and running pod install
2. Putting everything back in my podfile and running pod install

It's the only thing that worked for me.
