I added Firebase libraries to my project, and then I got this error. When I compile it, Xcode can\'t find some directories. However, they are in the Pods directory.
For me i had to change/edit the schema and choose the new one.
I had renamed my debug schema to debug(development) and that was causing my problem.
debug
debug(development)
Fix:
Product > Edit Schema > Change Build Configuration
What I did was create alternate Configurations and renamed my current one.
Configurations
