Cocoapods: Unable to find a specification for `Firebase/Core`

Question

I have this in podfile:

pod \'Firebase/Core\'
pod \'Firebase/Messaging\'

but getting this error:

[!] Unable to find

Answer 1

None of the approaches mentioned worked for me. Here is how I made it to work, however:

1. Comment out all of your pods in your Podfile.
2. Comment them back in one-by-one and run pod install after each
3. Clean and run

I hope it will help somebody.
